The hierarchy of domains descends from the right to the left label in the name; each label to the left specifies a subdivision, or subdomain of the domain to the right. For example: the label example specifies a node example.com as a subdomain of the com domain, and www is a label to create www.example.com, a subdomain of example.com. Each label may contain from 1 to 63 octets. The empty label is reserved for the root node and when fully qualified is expressed as the empty label terminated by a dot. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation.[6] Thus, when using a single character per label, the limit is 127 levels: 127 characters plus 126 dots have a total length of 253. In practice, some domain registries may have shorter limits.

A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet. In 2017, 330.6 million domain names had been registered.[1]
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.

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.


But, again, operationally it's quite strong. 24/7/365 customer support is available not only by live chat and email, but by phone. It offers free site migrations with some dedicated attention paid to making a transfer as smooth as possible. And, if you're willing to go for one of the higher-end plans, the company has put some serious attention into performance and caching.
One's website is placed on the same server as many other sites, ranging from a few sites to hundreds of websites. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this type of service can be quite basic and not flexible in terms of software and updates. Resellers often sell shared web hosting and web companies often have reseller accounts to provide hosting for clients.
An important function of domain names is to provide easily recognizable and memorizable names to numerically addressed Internet resources. This abstraction allows any resource to be moved to a different physical location in the address topology of the network, globally or locally in an intranet. Such a move usually requires changing the IP address of a resource and the corresponding translation of this IP address to and from its domain name.
Domain names are created to make IP addresses easy to remember. Every computer has an IP address assigned to it - much like a street address. But instead of having to memorize each IP address number, we assign domain names to these numbers so we can easily remember them. The domain name system, or DNS, takes domain names and translates them into their IP addresses so that computers can communicate with one another.
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.

For special purposes, such as network testing, documentation, and other applications, IANA also reserves a set of special-use domain names.[15] This list contains domain names such as example, local, localhost, and test. Other top-level domain names containing trade marks are registered for corporate use. Cases include brands such as BMW, Google, and Canon.[16]
If you register a domain with Bluehost when signing up for a hosting account, there is a domain fee that is non-refundable. This not only covers our costs, but ensures that you won't lose your domain name. Regardless of the status of your hosting service, you'll be free to manage it, transfer it after any required lock periods, or simply point it elsewhere at your convenience. You retain ownership of your domain until the end of its registration period unless you elect to extend it.

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."

The web hosting provider got bonus points for its policy of performing regular daily backups, even on the lowest-priced shared hosting accounts. Be aware, though, that the promotional price on the low-cost shared hosting does go up after the promotional period. That said, Bluehost offers 24/7 phone support, a 30-day money-back guarantee and SSH access for certain plan options.


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. 
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.
12. NamecheapThe service and the name of Namecheap certainly have much in common, given that it is probably your best bet of acquiring a low-priced yet high-quality domain name. For instance, .org domains are available for as low as $9.99 and purchased with a single click of a button, whether you’ve just come up with the title of your brand, or transferred a current name to the company’s professionals. Prices are equally affordable for high-performance shared hosting buyers and those interested in managed WordPress hosting (with or without a site on the popular CMS platform), and object to both monthly and annual subscriptions. They all get a hands-on kit of creation material, from site builders to site analytics. 

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]


In the early 21st century, the US Department of Justice (DOJ) pursued the seizure of domain names, based on the legal theory that domain names constitute property used to engage in criminal activity, and thus are subject to forfeiture. For example, in the seizure of the domain name of a gambling website, the DOJ referenced 18 U.S.C. § 981 and 18 U.S.C. § 1955(d).[29][1] In 2013 the US government seized Liberty Reserve, citing 18 U.S.C. § 982(a)(1).[30]
ICANN publishes the complete list of TLD registries and domain name registrars. Registrant information associated with domain names is maintained in an online database accessible with the WHOIS protocol. For most of the 250 country code top-level domains (ccTLDs), the domain registries maintain the WHOIS (Registrant, name servers, expiration dates, etc.) information.
You gain the most web-building functionality if you create a self-hosted site. This typically involves transfering the free WordPress CMS to server or signing up for a web host's optimized WordPress plan. With an optimized plan, the host automatically handles backend stuff, so you don't have to worry about updating the plug-ins and CMS, and enabling automatic backups. In these instances, the WordPress environment typically comes pre-installed on the server.

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.
We liked how Web Hosting Hub describes its new customer process. It tells new customers, "We walk you through setting up your account in a personal on-boarding call." The company has a few other wins as well. It offers an all-SSD infrastructure, automatic vulnerability patches and a custom firewall, SSH access for certain plans, free site migration and an excellent 90-day money-back guarantee.

Rounding out the wins, InMotion offers a full 90-day money-back guarantee. On top of that, here's a special money-saving hint. In a chat session confirming pricing and offerings, the operator offered me some special prices and deals that reduced the published price by a few bucks. I was also told that while promotional pricing does go up at the end of the offer period, if you contact customer service, InMotion has a "loyal customer discount" that may bring the price back down.
Domain names are often simply referred to as domains and domain name registrants are frequently referred to as domain owners, although domain name registration with a registrar does not confer any legal ownership of the domain name, only an exclusive right of use for a particular duration of time. The use of domain names in commerce may subject them to trademark law.

One thing we learned in reviewing the services listed here (and many more) is that even though the packages are very similar, they are not identical. Some are more security-focused than others, offering anti-spam and anti-malware tools. Others offer a variety of email marketing tools. While most of the hosts we've reviewed have built-in e-commerce, you may want to consider using a more-robust third-party online shopping cart application like Shopify instead.
I've been using your services for about 10 years. I just wanted to say thank you for your excellent service and support. Your support staff has always been so kind, helpful, smart and understanding. I'm a nervous nellie when it comes to doing this stuff (building websites), and you've walked me through the hard parts smoothly and efficiently. Seems I can always count on you.

In particular, Web Hosting Hub uses BoldGrid as a site builder. BoldGrid is actually an add-on to WordPress, so there's no lock-in. This overcomes the major problem of most site builders: you're locked into that host and that tool, often requiring you to completely rebuild your site if you want to expand. By using a WordPress-based solution, all of the rather considerable power of WordPress is available for future expansion.
CDNs not only help the stability of your website by distributing the traffic among different servers, they can also help to prevent cyber attacks.

HostPapa always aims to provide you with the best website hosting features to ensure your visitors are always pleased with your website.

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.
