A fully qualified domain name (FQDN) is a domain name that is completely specified with all labels in the hierarchy of the DNS, having no parts omitted. Labels in the Domain Name System are case-insensitive, and may therefore be written in any desired capitalization method, but most commonly domain names are written in lowercase in technical contexts.[2]

A fictitious domain name is a domain name used in a work of fiction or popular culture to refer to a domain that does not actually exist, often with invalid or unofficial top-level domains such as ".web", a usage exactly analogous to the dummy 555 telephone number prefix used in film and other media. The canonical fictitious domain name is "example.com", specifically set aside by IANA in RFC 2606 for such use, along with the .example TLD.
Some domain name registries, often called network information centers (NIC), also function as registrars to end-users. The major generic top-level domain registries, such as for the com, net, org, info domains and others, use a registry-registrar model consisting of hundreds of domain name registrars (see lists at ICANN[21] or VeriSign).[22] In this method of management, the registry only manages the domain name database and the relationship with the registrars. The registrants (users of a domain name) are customers of the registrar, in some cases through additional layers of resellers. 

A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities allow customers to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for websites that wish to keep the data transmitted more secure.
When it's time to set up shop, look for a web host that offers the aforementioned dedicated servers, as well as advanced cloud server platforms (such as Amazon Web Services or Google Cloud), custom server builds should you need it, and 24/7 customer support. Depending on your business' focus, you may need a web host that can handle pageviews or visitors that rank in the high thousands or millions. Many busy hosting plans offer an onboarding specialist that can help you get started, too.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
Shared hosting is web hosting in which the provider houses multiple sites on a single server. For example, Site A shares the same server with Site B, Site C, Site D, and Site E. The upside is that the multiple sites share the server cost, so shared web hosting is generally very inexpensive. In fact, you can find an option for less than $10 per month.
Some domain name registries, often called network information centers (NIC), also function as registrars to end-users. The major generic top-level domain registries, such as for the com, net, org, info domains and others, use a registry-registrar model consisting of hundreds of domain name registrars (see lists at ICANN[21] or VeriSign).[22] In this method of management, the registry only manages the domain name database and the relationship with the registrars.

GlowHost earned our kudos for its 91-day money-back guarantee. It's six days short of DreamHost's 97-day guarantee, but with these numbers, who's quibbling over a few days? The company also offers 24/7/365 phone support option and free cPanel offering for most plans. The company operates 18 data centers worldwide. Finally, the company garnered extra kudos by driving all its hosting services with wind power.
Next are third-level domains, which are written immediately to the left of a second-level domain. There can be fourth- and fifth-level domains, and so on, with virtually no limitation. An example of an operational domain name with four levels of domain labels is sos.state.oh.us. Each label is separated by a full stop (dot). 'sos' is said to be a sub-domain of 'state.oh.us', and 'state' a sub-domain of 'oh.us', etc. In general, subdomains are domains subordinate to their parent domain. An example of very deep levels of subdomain ordering are the IPv6 reverse resolution DNS zones, e.g., 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa, which is the reverse DNS resolution domain name for the IP address of a loopback interface, or the localhost name.

Second-level (or lower-level, depending on the established parent hierarchy) domain names are often created based on the name of a company (e.g., bbc.co.uk), product or service (e.g. hotmail.com). Below these levels, the next domain name component has been used to designate a particular host server. Therefore, ftp.example.com might be an FTP server, www.example.com would be a World Wide Web server, and mail.example.com could be an email server, each intended to perform only the implied function. Modern technology allows multiple physical servers with either different (cf. load balancing) or even identical addresses (cf. anycast) to serve a single hostname or domain name, or multiple domain names to be served by a single computer. The latter is very popular in Web hosting service centers, where service providers host the websites of many organizations on just a few servers.

I want to ask I’m a student and we will have an assignment in our school for next half year it’s my last year and this is project will decide my mark (grade). I want to make a blog and I don’t need any top-noch hosting for this. The site is potential going to be shut down after this project. So my question is do you recommend any of the hostings above.
During the 32nd International Public ICANN Meeting in Paris in 2008,[10] ICANN started a new process of TLD naming policy to take a "significant step forward on the introduction of new generic top-level domains." This program envisions the availability of many new or already proposed domains, as well as a new application and implementation process.[11] Observers believed that the new rules could result in hundreds of new top-level domains to be registered.[12] In 2012, the program commenced, and received 1930 applications.[13] By 2016, the milestone of 1000 live gTLD was reached.

Many web hosts offer limited features in their starter packages and then expand the offerings (sometimes tremendously) for higher-tier plans. Read the small print to make sure the plan you are selecting offers what you need. If you need a site builder application to design your website, make sure that the low-cost web host you are picking actually comes with a site builder. Many of them require you to pay for the builder as a separate add-on. Website builders usually don't cost a lot of money, but if you can find a web host that includes one for free, that's money in your pocket. And, if it's integrated with your hosting service, you're more likely to have a smooth, supported experience.

All of this infrastructure has been built out to support the a wide range of hosting services. The family-owned company gains points for understanding the importance of transaction security by offering free AutoSSL and Let's Encrypt SSL encryption for its plans. While the company offers sophisticated services for technically strong clients, it also has a Weebly web builder option to get you up and running quickly. 
Once you decide you price range, you need to consider how long you'll need web hosting. If it's a short-term project—say, less than a month or two—you can typically receive a refund should you cancel your hosting within 60 days. Some companies offer 30-day money-back guarantees, others offer 90-day money-back guarantees. Once again, it's beneficial to do your homework.
The first thing that caught our eye about Complete Internet Hosting was a great answer to my biggest complaint about hosting providers. Most hosting providers will suck you in with a relatively aggressive starting price, but when it comes time to renew, the renewal price can be two or three times the original price. I've even found one company that renews at more than six times the original price.
You can also host your website on WordPress.com, but that's different from the kind of hosting mentioned above. WordPress.com uses the same code from WordPress.org, but it hides the server code and handles the hosting for you. In that sense, it resembles entries in our online site builder roundup. It's a simpler but less flexible and customizable way to approach WordPress hosting. It's definitely easier, but if you want to tinker and adjust and optimize every aspect of your site, it might not be for you.
15. GreenGeeksIf you’re committed to renewable energy, you should give GreenGeeks a look. The hosting platform claims to be the cleanest hosting around, backed by 300% Renewable Energy Commitment. For prices as low as $3.95/month, users get unlimited space, transfer, email + free domain, and marketing services, which also make GreenGeeks one of the most compact, do-it-all hosting solutions on the market. You can acquire a Reseller package and manage multiple cPanel hosting accounts, request VPS hosting with dedicated resources and flexibility (and no additional expenses), or get an entire Dedicated server for extreme performance and flexibility. Next to cPanel, app hosting is also available for WordPress, Drupal, Joomla, and CMS. 
When it comes to server operating systems, Linux is typically the default option. Still, some services offer a choice of Linux or Windows hosting. If you have specific server-side applications that require Windows, such as SQL Server or a custom application written in .NET, then you need to make sure your web host has Windows hosting. But don't let the idea of a Linux host intimidate you. Nowadays, most web hosts offer a graphical interface or a control panel to simplify server administration and website management. Instead of typing at the command line, you'll click easily identifiable icons.
Many web hosting services offer so-called unlimited or unmetered service for whatever amount of bandwidth, disk storage and sites you use. It's important to understand that most terms of service actually do limit the definition of "unlimited" to what's considered reasonable use. The bottom line is simple: if you're building a pretty basic website, unlimited means you don't need to worry. But if you're trying to do something excessive (or illegal, immoral or fattening), the fine print in the terms of service will trigger, and you'll either be asked to spend more or go elsewhere.
Many web hosting services offer a low "starting price," but require you to prepay for two or three years of service to get that price. After the promotional period, the renewal price for some web hosting services can be two, three, or even four times the initial promotional pricing. While the initial deal might be incredible, the cost of transferring your site (or paying the added fee) in a couple of years may be something to consider.

18. Host1PlusHost1Plus is a unified solution for VPS hosting, fast cloud storage, IPv4 & IPv6, and full DNS control. It comes with powerful API, KVM virtualization, and custom ISO for Windows and Linux users. The scalable architecture allows Host1Plus to follow your growing demands, and boost all necessary resources with both managed and unmanaged plans. All unmanaged plans are TUN/TAP/PPP enabled and come with SSD caching, 500 Mbps uplink, Virtuozzo & OpenVZ, backups, and RAID data storage for up to 32 IPv4 addresses. You can use Host1Plan to create your domain zones and edit records directly at your Client Area, and control several Linux OS instances (Ubuntu, Fedora, Debian, CentOS, and Suse). You can also connect your virtual console to their emergency console to retrieve access to your server, and protect your data.
In housing terms, VPS hosting is like renting your own apartment in a larger building. You're much more isolated than in the roommate situation mentioned above; it's still possible that a neighboring apartment could causes annoyance for you, but far less likely. In web hosting terms, Site A's traffic surge won't have nearly as much impact on Site B or Site C. As you'd expect, VPS hosting costs more than shared hosting. You'll pay roughly $20 to $60 per month.
Doteasy have been absolutely fantastic over the years. The customer support team have always gone out of their way to help us and they have hosting packages available that help you to grow in an affordable organic way. When I first started, I knew nothing about websites, yet I was still able to get a project off the ground pretty easily. I can honestly say, I am not sure things would have progressed this far without their help.
US-based GoDaddy is one of the largest web hosting companies around. As one of the few that’s done television advertising, it’s probably the best known, too. Even its cheapest web hosting package comes with 100GB storage, unmetered bandwidth, and a free domain – with plenty of options due to GoDaddy's vast domain name repository. GoDaddy also boasts a guaranteed 99.9% uptime, free backup and restore, and expert hosting support available 24/7, all year round.

10. DreamHostDreamHost is another awarded web and WordPress hosting provider where you can get your brand new .xyz, .life, .online, .tech. or .store domain. Their most popular feature is the Remixer—an intuitive website builder that takes literally minutes of your time. It will allow you to attach a fully functional site on the web without resorting to any third-party service. Design aficionados, nonetheless, should not be discouraged by the all-in-one offer—Remixer is probably one of the most flexible and ready-to-configure builders out there. It will supply them with a unique and optimized theme that can only facilitate this process. Managed WordPress hosting for an existent site is also a valid option, and so are shared and email hosting with fast SSD storage, Virtual Private Servers with ultra-fast SSDs, and flexibility with HTTP/2, Ubuntu, IPv6, NGINX and Node.js, and dedicated hosting with 100% uptime guarantee. 
To host a website on the internet, an individual or company would need their own computer or server.[7] As not all companies had the budget or expertise to do this, web hosting services began to offer to host users' websites on their own servers, without the client needing to own the necessary infrastructure required to operate the website. The owners of the websites, also called webmasters, would be able to create a website that would be hosted on the web hosting service's server and published to the web by the web hosting service.
Allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and provide the technical support themselves.

The web hosting provider offers solid plans with a good selection of features. The one area we're concerned about is how it presents its offers. Like many hosting providers, its published pricing is a bit misleading. You're not getting hosting for $2.96/mo unless you pay $71 for two years of service. Renewals are generally at a higher rate, although a salesperson we spoke to advised you ask for a "loyalty discount."

I just wanted to recognize these two employees as they are both amazing. I spoke to Ken and he helped me with my site statistics and setting up a bunch of other things. He was so patient and knowledgeable. Eric, I spoke with on the next day as I was setting up my mobile site view and he was amazing too and even gave me a call back as he tried to change something for me. Anyway they are both amazing. Great customer service!

Toby Sembower built and hosted his first website in 1998, when the Internet was often annoyingly referred to as "the information super-highway." Toby is the first to admit that site was plain terrible. Nonetheless, it piqued his interest in the Web, and he would go on to build, own, and operate (and host externally) sites totaling 100+ million visits on a variety of subject matters. Today Toby is CEO at Digital Brands Inc., a fast-growing firm that owns and operates a number of popular web properties.

The practice of using a simple memorable abstraction of a host's numerical address on a computer network dates back to the ARPANET era, before the advent of today's commercial Internet. In the early network, each computer on the network retrieved the hosts file (host.txt) from a computer at SRI (now SRI International),[4][5] which mapped computer hostnames to numerical addresses. The rapid growth of the network made it impossible to maintain a centrally organized hostname registry and in 1983 the Domain Name System was introduced on the ARPANET and published by the Internet Engineering Task Force as RFC 882 and RFC 883.
A dedicated server is best suited to anyone looking to build complex websites that need to look after hundreds of users in a no-compromise environment. (Think Amazon.) It’s like having your own computer: you don’t have to share your space, power or resources with anyone else. Dedicated servers are usually the fastest and most powerful choices available, though some of the high-end VPS options can give the lower performing dedicated servers a run for their money – so check the specs.
Finally, we were quite happy with their money-back guarantee. They offer a full 90-day guarantee (except for domain names you buy) and a pro-rated refund for the rest of your time. So if you want to cancel after 18 months and have six months left in your term, you'll get back the cost of the six remaining months. It's clear, it's understandable, and it's the straightforward way we'd like to see most providers use as a model.
Many web hosting services offer a low "starting price," but require you to prepay for two or three years of service to get that price. After the promotional period, the renewal price for some web hosting services can be two, three, or even four times the initial promotional pricing. While the initial deal might be incredible, the cost of transferring your site (or paying the added fee) in a couple of years may be something to consider.
If you're not sure of the type of hosting your business needs, you might want to start small, with shared Web hosting. You can always graduate to a more robust, feature-rich package of, say, VPS hosting or even dedicated hosting in the future. Unfortunately, some hosts don't offer all hosting types. Consider how much you expect to grow your website, and how soon, before you commit to anything longer than a one-year plan. It's worth spending the time up front to make sure that the host you select with is able to provide the growth you envision for your site, as switching web hosting providers midstream is not a trivial undertaking.

There are also a few other alternative DNS root providers that try to compete or complement ICANN's role of domain name administration, however, most of them failed to receive wide recognition, and thus domain names offered by those alternative roots cannot be used universally on most other internet-connecting machines without additional dedicated configurations.
Domain names are often seen in analogy to real estate in that domain names are foundations on which a website can be built, and the highest quality domain names, like sought-after real estate, tend to carry significant value, usually due to their online brand-building potential, use in advertising, search engine optimization, and many other criteria.
Similar to the dedicated web hosting service, but the user owns the colo server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's machine, providing only the electrical, Internet access, and storage facilities for the server. In most cases for colo, the client would have his own administrator visit the data center on site to do any hardware upgrades or changes. Formerly, many colocation providers would accept any system configuration for hosting, even ones housed in desktop-style minitower cases, but most hosts now require rack mount enclosures and standard system configurations.

Critics often claim abuse of administrative power over domain names. Particularly noteworthy was the VeriSign Site Finder system which redirected all unregistered .com and .net domains to a VeriSign webpage. For example, at a public meeting with VeriSign to air technical concerns about SiteFinder,[25] numerous people, active in the IETF and other technical bodies, explained how they were surprised by VeriSign's changing the fundamental behavior of a major component of Internet infrastructure, not having obtained the customary consensus. SiteFinder, at first, assumed every Internet query was for a website, and it monetized queries for incorrect domain names, taking the user to VeriSign's search site. Unfortunately, other applications, such as many implementations of email, treat a lack of response to a domain name query as an indication that the domain does not exist, and that the message can be treated as undeliverable. The original VeriSign implementation broke this assumption for mail, because it would always resolve an erroneous domain name to that of SiteFinder. While VeriSign later changed SiteFinder's behaviour with regard to email, there was still widespread protest about VeriSign's action being more in its financial interest than in the interest of the Internet infrastructure component for which VeriSign was the steward.
Having multiple servers hosting the same content for better resource utilization. Clustered servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Usually web hosts use clustered hosting for their shared hosting plans, as there are multiple benefits to the mass managing of clients).[9]
