Web Hosting, Domain Name System, DNS Protocol, DNS Resolver, Web Hosting Reviews

DNS is the abbreviation of Domain Name System which is a stratified naming system for services, computer and for any other possessions attached to the network or internet. DNS (Domain Name System) is responsible to links a variety of information with domain names allocated to each of the participants. The main task of DNS (Domain Name System) is the translation human language into the binary code. It is also serve as the distributed database that offers mapping among Internet Protocol addresses and host names. DNS makes facilitate the client to consign a domain name to groups of internet users in a significant way.

The DNS (Domain Name System) share out the conscientiousness of conveying domain names and mapping those names to IP addresses by delegating trustworthy name servers for each domain. Authorized name servers are consign to be accountable for their exacting domains, and then allocate other reliable name servers for their sub-domains. This method has through the DNS (Domain Name System) circulated and error understanding and has helped keep away from the need for a single central register to be constantly asked and updated. Usually domain name system restores different types of data such as mail server list that recognize email for a specified internet domain. In short DNS (Domain Name System) is a compulsory part of the functionality of the internet.

DNS Protocol


The DNS protocols contain various kinds of DNS messages that are progressions according to the data in their message fields. DNS protocols consist of message type which consists of queries; updates, and responses, DNS (Domain Name System) query message format has fixed length which is 12 bytes. DNS Header has fixed length and all other such as Question Entries, Answer Resource Records, authority Resource Records, Additional Resource Records have variable length. There are many other type of DNS (Domain Name System) messages or protocol such as DNS query message header, DNS query question entries, DNS resource records, Name query message, Name query response, Reverse name query message, DNS update message format, DNS (Domain Name System) update message flags, Dynamic update response message.

DNS resolvers


The DNS (Domain Name System) client side is called DNS resolver which is responsible for starting and sequencing the inquiries that eventually guide to a complete resolution of the sources required. DNS resolvers and DNS server are performing recursively on behalf of the resolver.

Resolving typically involve iterating through numerous name servers to locate the desirable information. Some resolvers purpose simplistically and can converse only with a particular name server and these all called stub resolvers which are rely on a recursive name server to execute the work of finding information for them.

DNS related files


DNS (Domain Name System) consist of boot which is a BIND boot configuration file, Cache.dns use for uploading, Root.dns which is a root zone file, and zone_name.dns which is a used when any zone entered and configured for a server.

DNS Resource Records


DNS Resource Records contains alphabetic list such as A which is a Host address (A) resource record, AAAA which is a IPv6 host address (AAAA) resource record, AFSDB which is a Andrew File System Database (AFSDB) resource record, ATMA which is a Asynchronous Transfer Mode address (ATMA) resource record, CNAME which is a Canonical name (CNAME) resource record, HINFO which is Host information (HINFO) resource record, ISDN which is a Integrated Services Digital Network (ISDN) resource record, KEY which is a Public key resource record, MINFO which is a Mailbox mail list information (MINFO) resource record, MX which is a Mail exchanger (MX) resource record, NS which is a Used to map a DNS (Domain Name System) domain name, etc.

DNS Architecture


The DNS Architecture consist of the following

Domain name space


Domain name space included a hierarchy of domain names and every node has zero or many source record having information linked with the domain name. The domain name space tree divided into zones starting at the root zone. A DNS zone contains of a compilation of linked nodes convincingly served by authorized name server because a single zone can host multiple server at a time.

Domain name formulation


Domain name formulation contains one or many parts which is technically called labels that are usually concatenated, and surrounded by dots. The right label express the peak level domain and it move down from right to left .every label to the left side classify a subdivision of the domain to the right. Each label has 63 characters and not surpasses a total length of 253 characters. Technically contains character signify as octet. The ASCII characters are allowed and included A to Z and 0 to 9, and hyphen. It is called LDH rule. The domain name relate as a minimum one IP address.

Internationalized domain names


The allowable character set of the DNS prohibited the demonstration of names and words of a lot of languages in their inhabitant alphabets or scripts. The IDNA system has approved by ICANN which diagram Unicode strings into compelling DNS character set. ICANN accepted the installation of IDN country code domain.

Name servers


The DNS system is upholder by a dispersed database system. This system employs the client server model and the knobs of database are the name servers. Every domain has minimum one authorized DNS server which distributed information about domain and name server of every domain subsidiary to it.

Authoritative name server


It is a name server which is responsible to answer about the configuration that it is held by an original source. Only Authoritative name server returned answer to inquiries related to domain name that have been exclusively configured by the administrator. Authoritative name server can be whichever slave master which uses an automatic method of the DNS protocol in contact in the company of its master server which maintains alike copy of the master account. Each zone of DNS ought to be a set of authoritative name servers. After the registration of domain name their setting up has need of the assignment of a primary name server and minimum one secondary server. The necessity of manifold name servers intends to make the domain still practical yet if one name server happen to unreachable or untreatable. The title of a primary name server is exclusively resolute by the precedence specified to the domain name registrar. For this reason usually only the completely competent domain name of the name server is compulsory.

Recursive and caching name server


The authorized name servers are enough for the process of the Internet. While with the authoritative name servers working Each DNS inquiry should start with recursive inquiries fro the root zone and every user have to employ resolved software competent of recursive operation. The effectiveness can be improved by dropping DNS traffic across the internet and boost performance in end user. DNS cache servers also supported by Domain name system which has ability to store information for a long period resolute in the configuration and these caching DNS server also called DNS caches. The amalgamation of DNS caching and recursive functions in a name server is not obligatory. These all can be put into practice separately in servers for particular reasons. All ISP commonly offer caching and recursive name servers for their client.

DNS and Active Directory


The active directory of windows server uses DNS as its domain manager location system. For any type of task such as updating, authentication, searching etc any computer based on window server use DNS to allocate domain controller of active directory and all these domain controller use DNS to trace each other.

DNS and WINS

The previous means of name declaration for a Windows network was WINS. DNS is unlike than WINS because WINS is flat and DNS is hierarchical name space. Those clients and application rely on NetBIOS prolong to use WINS for name declaration. WE can get maximum competence by the mixture both WINS and DNS for a variety of network resources and services.

DNS and DHCP


For DNS server of Widows the DHCP service offers default carry to register and update information for inheritance DHCP clients in DNS sector. DHCP integration facilitate a DHCP client that is incapable to dynamically update DNS sources records straightforwardly to have this information updated in DNS onward and undo lookup zones by the DHCP server.

Parked Domain, Addon Domain, Subdomains, Web Hosting, Compare Hosting

What is the difference between parked, addon, and subdomains?


Customers who are new to the hosting industry, at times, get confused between the control panel – parked, addon, and subdomains.

Here is a brief explanation of what it is all about so that you know what you should be going for, to match your requirements.

1. Subdomain


As the name suggests, it does not have a new domain name. It is a is a second website, with its own unique content, but will always carry the name of the parent/main domain.

As an example, you have the domain domain1.com. Its document root will be /home/username/public_html (this could vary at times). Contents will be loaded from this location when domain1 is accessed in the browser.

You decide to have a wordpress installation in a sub directory blog (/home/username/public_html/blog), which you intend to access as blog.domain1.com

This is when you go for a subdomain. The same contents can be accessed as domain1.com/blog or blog.domain1.com

If you own domain1.com, you can have many subdomains (depending on the plan you are on) as blog.domain1.com, help.domain1.com, gallery.domain1.com

2. An addon domain is a second website, with its own unique content. This type does require you to register the new domain name before you can host it.

You host domain1.com and would also want to host domain2.com too. You then need to register domain2.com and add it as an addon domain under the hosting account of domain1.com.

The document root would normally be /home/username/public_html/domain2.com (in this case),

The addon domain will look completely independent to the outside world with no means for anyone to know that this is running on an account under another site.

There are 3 ways of accessing an addon domain:

a. domain2.com

b. domain1.com/domain2.com

c. domain2.domain1.com

3. Parked Domain


A parked domain is NOT a unique website. This is a mechanism where you would want more than one domain name to point to the same website.

You have a main domain domain1.com to which you want to point domain2.com, domain3.com and domain4.com

All you need to do is add domain2.com, domain3.com and domain4.com as parked domains of domain1.com. Anyone accessing any of these sites will be greeted with the contents of domain1.com

Parked domains, again, would require you to register the domain names in order to use them.

Web Hosting, Web Hosting Reviews, Compare Hosting, Hosting Learning

It seems as if everyone has their own definition of cloud and hosted services. In truth, cloud and hosted are very similar — both are off-premise and are accessed through an Internet connection. While some believe that these services are essentially the same, experts argue that cloud services are more interrelated with other web-based offerings. When it comes down to it, the main difference between the two services is multi-tenancy.

Multi-tenancy


Multi-tenancy implements the sharing of resources and costs among a large pool of users and allows infrastructure to be concentrated in locations with lower costs, maximizing peak-load capacity and improving utilization and efficiency in systems that are often only used up to 10 to 20% of the time. Hosted services generally do not offer the same cost efficiencies, elasticity, or reliability as cloud services. As a result, cloud computing is more fitting for disaster recovery and business continuity.

The benefits for the cloud provider are amplified by only having to support a single version of software, the uniformity of its hardware environment, and its efficiency. The general rule is that if a solution is not multi-tenant, then it isn’t a cloud solution, and won’t have the same benefits.

Hosted Services


Hosted services are technology services offered by a provider hosting physical servers that are removed from the customer’s premise. A hosted service provider owns and oversees infrastructure, software, and administrative tasks at a private location. The system is available to clients, typically through a direct network connection that uses the Internet (VPN, Remote Desktop, etc.). There are three main elements of this service: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). These three combined encompass software, network capacity, and the equipment used to support operations such as storage, hardware, servers, and networking components.

Cloud Services


Cloud services are a subset of hosted services. Hosted services, even those accessible using the Internet, cannot be referred to as real cloud solutions unless they have been built to capitalize on the collaboration and interconnectivity that is a fundamental part of the cloud. Cloud applications are web-enabled, meaning, instead of being based on physical hardware, they are based in a shared virtual environment managed by a cloud-hosting provider. Only server installation and a device with an Internet connection are needed. Many line-of-business (LOB) applications are adding this functionality to their offering. Cloud servers can be constructed to provide varying levels of performance, security, and control to configure to your business’s needs.

Cloud servers allow your business to optimize IT performance without the overwhelming costs associated with the purchase and management of fully dedicated infrastructure. These servers are the ideal fit for businesses of variable demands and workloads. Cloud services offer on-demand utilities, multi-tenancy features with seamless uninterrupted scaling, and features that are sure to meet your business’ needs to adapt and help you meet the demands of your client base.

Free Website Hosting, Web Hosting Reviews, Web Hosting Guides, Compare Web Hosting
As the name suggests, free website hosting is a free non-paid web hosting service. There are many web hosts who provide subdomains to anyone who want to make website. Some of such popular free web hosts include Blogger and Wordpress. When you make your websites with these free website hosting services, your website gets such name as yoursite.blogspot.com and yoursite.wordpress.com. If you want to get a website with a domain name that doesn’t include any external site’s name, you must buy domain and then get web hosting which is usually a paid service. However, there are many web hosting companies that provide free web hosting with some or the other products/services that you buy from them.

Benefits of Free Website Hosting


There is this single biggest advantage of free website hosting and that is- it comes free without any cost. Now if you are amazed at why these free web hosting companies let you make a website free of cost then you may rest assured that they do not make any loss in this business. When you make your free website with them, they use your websites to place advertisements, banners and other forms of advertising media to earn revenue. Sometimes, the revenue from advertisement is shared with the owner of the website and sometimes it’s not. For example, when you get free web hosting from blogger and if you use their AdSense service, you get a share in the revenue generated from the advertisements that they place on your websites. On the other hand, when you make a free website using wordpress, you do not have any control on the placement or revenue generated from your free hosted website. The situation is altogether different when you get website hosted through paid web hosting service. You have full control over your website and it’s your decision whether you want to place advertisements on your site or not and if yes then the whole of the revenue generated from the website advertisement banners come to you only. There are many other differences between free and paid web hosting services.

Differences between Free and Paid Web Hosting


Here are some major differences between free and paid website hosting services. It will give you a better understanding about what is free web hosting service and whether it’s worth to opt for such free hosting for websites?

Advertisements on your website are controlled by the web hosting company that provides you with the free web hosting. It can use pop-ups, banners or any other advertisement on your site on which you do not have control. If also you have partial control, you may only decide what size of banner would be displayed where on your site. You won’t have control over what advertisement you will show on the website. On the contrary, when you avail paid web hosting, you have full control over your website and no outsider can decide anything for it.

Customer support is missing for free website hosting. Something which comes free cannot be asked to come with value added services. If something goes wrong with your website, there’s no customer support for websites made with free hosting. On the other hand, paid web hosting services not only give technical support to the customers but they also provide them with help guides, tutorials etc.

Low bandwidth and lesser data transfer capacity makes free website hosting vulnerable to greater downtime whereas paid website hosting gives you optimum bandwidth and data transfer for maximum uptime. You also can’t upload more images or videos when using free web hosting service as you don’t get enough disk space.

However, you can have best from the both worlds if you are ready to pay a little amount for any service that a web hosting company offers. For example, we offer a good web hosting package which comes with free online website builder and you have to just pay nominal rates. You get web hosting free along with many other facilities and services like email ID and free Google Adwords credit that you may use to advertise your website. This offer is better than any free website hosting service as you get full control over your website at practically very low cost! So, why wait!

Modern-day businesses are beginning to realize the importance of agile hosting services. It has become evident that the quality of hosting will determine the success of several crucial parameters such as SEO, bounce rate reduction, customer retention, and to an extent even the sales numbers. Given the relevance of these factors in determining the success of any business, companies have begun to look for faster and better hosting services.

SSD VPS Hosting, HDD VPS Hosting, Hosting Reviews, Hosting Guides, Compare Hosting

Gone are the days when companies would rely solely on the options provided by their website developers. Today, companies research the best possible solutions and evaluate what may be ideal for them. While most organisations have already made the move from Shared to VPS Hosting, smart organizations are diving further to determine the benefits between SSD vs HDD VPS Hosting. Let us try to find out what is the difference between Solid-State Drive and Hard Disk Drive along with your best possible option.

Mechanism


Before we take a look at the difference between SSD and HDD, it is vital to understand the underlying working mechanism of both technologies. HDD is a decades-old technology based on the mechanism of vinyl records. The HDD drive stores data in patterns magnetically. It has a thin metal disk which rotates at 7200 RPM to record and read data. Each driver is equipped with sensors capable of reading the data and sending it back to the motherboard.

The problem, however, arises with the fact that the disk will approximately spin 3.8 billion times a year leading to wear & tear and eventually some mechanical failure. On the other hand, SDD does not contain any moving parts. It stores data on interconnected flash memory chips. It can be seen as an upsized and advanced version of the regular pen drives. SSD uses a NAND-based flash memory making it more secure even when the device is turned off.

Speed


The working mechanism plays a significant role in dictating the outcome of SSD vs HDD Speed tests. HDD is equipped with moving parts bringing lesser read speeds and write speed as compared to SSD. SSD with its NAND flash memory is capable of clocking substantially high read and write speeds. The rotational latency in HDD leads to lower speeds when compared to SSD.

It is obvious that hosting servers employing SSD will offer better speeds than service providers using HDD storage. A faster loading website will give a significant boost to your SEO and improve your Google ranking. Search engine algorithms give importance to the website loading time in determining the rankings. Google and other search engines rewards websites with faster loading times as it provides better customer experience.

A faster loading website also gives a better customer experience as they can navigate without any lag and waiting time. Also, with the attention span of viewers reducing with ever increasing internet speeds, you have a narrow window to attract a customer before they decide to switch to another website. Web hosting with SSD ensures that your customer is delighted to visit your site and use your product or services.

Data Security


Data security is another crucial parameter that can severely affect your organization. The hosting servers are operational 24*7 which is different from the production environment. Overloading of hardware with I/O requests can lead to the failure of the hard disk. Such a failure could cause your website to go offline and raise uncertainty over the recovery of your data. While most data centres do keep a backup of the data, but there is always a possibility that you may lose some due to unforeseen circumstances. It is worth noting that the cost of data recovery with HDD is higher than that for SSD.

SSD comes with faster processing time reducing the risk of failure due to increased I/O requests. These also do not have any mechanical parts that could undergo wear & tear over a period of time and lead to mechanical failure. So, your data is extremely secure with SSD VPS hosting.

Environmental Factors


The usage of SSD drives in data centres results in lower power consumption when compared with the power consumed by the HDD drives. This is because the latter generates heat due to the mechanical moving parts and needs more energy to cool down. SSD drive, on the contrary, does not generate any such heat during its operation. Besides saving the environment, opting for SSD VPS hosting will also save your financial resources as the plans are comparatively cheaper.

With cloud computing well into the mainstream and steadily replacing roles currently filled by traditional server architecture, it’s time to ask the big question: can cloud hosting replace traditional file servers for storing and sharing files between employees in your organization? Serving, sharing, and storing files was probably the very reason many small and midsize companies built out their intranet infrastructure in the first place, and may still be the only reason that many companies have a server in their office or are renting server space. And as the workforce became more mobile, these servers took on the additional duties of sharing your internal files with employees on the road or working from home, even though they may not have always been designed for those functions.

Cloud Hosting, File Servers, Web Hosting Reviews, Compare Hosting

Cloud hosting, on the other hand, was born from a networked world with sharing, collaboration, and mobility being key considerations from the very beginning. Despite only being a relatively recent technological innovation, cloud computing has leveraged these strengths to quickly start eating away at the share of file hosting and file sharing duties of traditional server setups. Still, many companies are still hesitant to trust their files and security entirely to a third party where they may share space and resources with other companies, or entrust their proprietary data to some nebulous “cloud”. So which is better for your needs? What are the pros and cons of legacy file sharing servers compared to the newcomer cloud storage?

Traditional File Servers: Pros And Cons


File servers have been the mainstays and workhorses of the business world practically since business networking has been a term. There are a significant number of pros to keeping your files on an internal (or externally managed) server that you control. The biggest pro is ownership. While you may not own a rented server, if you are on shared hosting for example, you still control all of the contents of the server without doubt, and a hosting company cannot simply pull the plug on you, erase your data, or otherwise compromise the integrity of your data. This is even more so if you actually host your own file server on–premises or in a colocation space.

Another advantage of maintaining your own file server is the ability to configure it as much as you want, within certain limits (depending on your server type–self–hosted, shared, or dedicated). This gives you options about how you want files served, how credentials will be assigned, where people will be able to access files from, etc. This gives you flexibility and allows you to set things up in a way that is unique and specialized for your organization.

The major downside of having a traditional file server for sharing is the inflexibility and difficulty in maintaining such a server. Whether you host the server on–premises, have a shared hosting account, or a dedicated or co–located server, it is difficult to scale up and down as demand rises and falls. In fact, it’s impossible to do so dynamically in real time. That means during slow periods, you may be paying for way more server than you need, while during especially busy periods you may find that you are running out of bandwidth, RAM, or storage space. On top of that, unless you use a managed server, you will also have to be responsible for your own security and maintenance.

Cloud Storage: Pros And Cons


Cloud storage has pros that are the exact opposite of traditional servers. In order to utilize public cloud servers for storage and file sharing, you will be giving up a large portion of control in exchange for smooth operations. Public cloud storage allows you to not have to worry about buying server space, maintaining security, provisioning file space, or any of the other tasks that owning a server usually entails. The cloud storage provider will be responsible for security, for determining how access is granted, and where people can access the server from. You also gain flexibility. Many cloud storage services allow you to ramp services up and down to keep up with real–time demand. In fact, some will even do the automatic provisioning for you.

Downsides of a cloud storage and sharing solution are the loss of control that such a solution entails. You also have to worry about the cloud storage provider becoming a victim of cybercrime attacks. While most cloud service providers are much more security savvy than most small business IT teams, they are also much more likely to be seen as targets by hackers and other malicious elements.

Ultimately, each solution to the problem of file sharing and storage has its own pros and cons. Which works best for your business largely depends on your needs and your capabilities: a file server for companies with an IT budget to spend but a need for privacy, extra security, or their own special server build, or cloud storage for companies that don’t mind giving up a large measure of control in exchange for costs savings in IT management and technology.

Shared Hosting, WordPress Hosting, Web Hosting Learning, Compare Hosting

When creating a website, one of the most important decisions you’ll make is what type of hosting
plan to purchase. If you use a platform like WordPress, you’ll need hosting in order for your website to be available online. What’s more, selecting the right option is vital.

Two of the most popular choices for first-time website owners are shared hosting and WordPress hosting. Shared hosting is a type of low-cost plan where you share space on a server with other sites. WordPress hosting (which can be shared or not) means that the server comes optimized with the specific platform in mind.

In this post, we’ll talk you through your main hosting options, and explain how to find a plan that suits your needs. Let’s get started!

An Introduction to Shared Hosting


Put simply, a web hosting plan is a service that enables you to rent space for your website on a server. This is what gets your site online, and enables people to visit it. There are many different types of hosting plans available, however, and each one differs in terms of price and potential benefits.

Read More: Shared Web Hosting

One of the most common options is a shared hosting plan, where a single server is split between multiple websites. This is in contrast to dedicated hosting, where a single site has a physical server all to itself. Shared hosting is a popular choice for new and smaller sites, largely due to its low cost (often $5 per month or less).

While price is the primary benefit, there are some potential downsides to this kind of hosting. You’ll have to share resources with other websites, for example, which means your performance can suffer if those sites get a lot of traffic. Security can also be a concern, although a quality provider will offer additional protections.

What’s more, a standard shared hosting plan is not your only option. You can also opt for something more specific to the platform you’re using.

The Differences Between Shared Hosting and WordPress Hosting


As the name suggests, WordPress hosting is web hosting that has been optimized for the needs of a WordPress website. It’s important to understand that this isn’t a type of plan in the same way that shared hosting is. WordPress hosting can be shared, dedicated, or something else entirely.

What matters is that WordPress hosting better meets the performance and security needs of sites built using the platform. You may also get access to platform-specific features such as pre-installed sites, automatic WordPress updates, and dedicated WordPress support.

The details of your plan will depend on the provider you choose, of course. In addition, many hosts also offer both managed and unmanaged WordPress hosting plans. Unmanaged plans leave site optimization and server management up to you. A managed plan is slightly more expensive, but provides you with a lot more help keeping your site running smoothly.

How to Decide Which Type of Plan Is Best for Your Site


Both traditional shared hosting and WordPress hosting are viable options, making it difficult at times to choose the right one. However, directly comparing the two can make the decision easier.

Especially when you’re first starting out, one of the main criteria to consider is cost. As previously mentioned, shared hosting is about as cheap as it gets. This makes it a perfect option for those setting up new websites and blogs.

However, you’ll find that shared, WordPress-specific hosting plans can be almost or just as affordable as more platform-agnostic options. For that reason, it’s well worth looking into a WordPress hosting plan for most sites. A WordPress plan will be carefully designed to address the needs of your specific site, which is a significant benefit.

If you have the budget for it, you may also want to look into managed WordPress hosting. While these plans are often pricier, you’ll have a more efficient and secure site that’s taken care of by platform experts. This is an especially strong option for those completely new to WordPress, as well as business owners who don’t have the time or expertise to handle performance and security concerns personally.

Ultimately, there’s no one ‘correct’ choice of hosting for every website. You’ll need to assess the individual needs of your business and site. However, most WordPress users will be better off with a plan that takes their specific needs into account, whether that’s a shared option or something more powerful.
