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 should also avoid words that have more than one spelling if your visitors are likely to be confused and mistype the name. Alternately, you can buy both versions of the name and direct visitors from the one you like less to the preferred name. While you do want a short name (see below), don’t go for something so cryptic that people have a hard time remembering it. Word of mouth is a powerful marketing tool and you want to make it easy for people to tell their friends about your site.
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]

When you type google.com into your browser, the domain is split into parts by the “dot”, from right to left. The first part is “com”, so your computer checks the root zone file to see which registry manages the .com TLD. It then checks with this registry to see where the next part, “google”, points to. The registry returns the IP address 216.58.214.14, and your computer can then ask Google to send their homepage over.
Avoid having numbers in your domain name. People can get confused about whether the numbers is a digit (3) or a word (three). If you want a number in your domain name because there’s a number in your company name, buy both versions (digit and word) and redirect one to the other. Be especially wary about using the number “0” in a domain name as people may see it as the letter “O.”

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.

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.
One of the most important decisions in establishing an online presence is choosing a domain name. The right domain name for your website is important, for both your target audience and search engines. Ignore the trends and fads of the day and choose a name that makes sense for your business or subject matter now and will still make sense 10 years from now. Here are 10 tips to help you make a good domain name purchase.
1and1 have terrible customer service and billing, quite possibly the worst ever encountered. Their billing/invoice system is all over the place, their staff untrained and unwilling to resolve and their pricing is literally plucked out of thin air. Beware, pay 12 months in advance (not monthly) then cancel the direct debit or Paypal auto payment, otherwise they will rinse your pockets when you’re not looking &/or unexpectedly take an extra payment because of an ‘oversight’.
Avoid having numbers in your domain name. People can get confused about whether the numbers is a digit (3) or a word (three).

A domain name can be used for a variety of purposes. Many people who are not ready for a website simply register the domain name of their choice to ensure it doesn’t get snatched up by anyone else. They may use it to create a professionally branded email address, or as a Web address that can point customers to an alternate online presence, such as their social media page, if they don’t yet have a website.
Intercapping is often used to emphasize the meaning of a domain name. However, DNS names are not case-sensitive, and some names may be misinterpreted in certain uses of capitalization. For example: Who Represents, a database of artists and agents, chose whorepresents.com,[citation needed] which can be misread as whore presents. Similarly, a therapists' network is named therapistfinder.com. In such situations, the proper meaning may be clarified by use of hyphens in the domain name. For instance, Experts Exchange, a programmers' discussion site, for a long time used expertsexchange.com, but ultimately changed the name to experts-exchange.com.[citation needed]
Domain names put a friendly face on hard-to-remember numeric internet addresses. Every computer on the internet has a unique internet protocol (IP) number. A domain name represents one IP number or more. For example, the IP number for the domain name whitehouse.gov is 104.109.178.94. The whole purpose is to give users an easy-to-remember handle so that when sending an e-mail to, let's say, the President of the United States, you can type president@whitehouse.gov instead of the more unwieldy president@104.109.178.94.

Registering a domain name lets you create a personal presence on the web. With your own web address, you can control your online identity by linking to any other site with more information about you. For example, you can register a domain name and forward it to a website, blog, or social profile page like your Facebook, LinkedIn, or Twitter pages. A domain name can protect your personal brand and help your career.

Hostt is a just-launched free web hosting company that includes domain name purchasing and registration. They've a suite of offerings, such as one where you'll pay $13.99 per year for domain names with extensions that include .com, .net, .org, .us, .biz, and .info., but have unlimited bandwidth, web space, sub-domains, parked domains, sub-domains and email accounts, among other things. Like HostGator, they include domain locking and automatic renewal, along with a user-friendly management portal (which, believe me, is pretty rare) and 24/7 technical support. This isn't a bad price considering the amount you get, and their $3.95 and $5.95 a month packages both offer fairly balanced domain-inclusive packages.
When registering a domain, the name, address and phone number you submit must be published to the WHOIS directory. Your information is public and accessible to anyone, at any time and is required by the Internet Corporation for Assigned Names and Numbers (ICANN) as part of the domain registration process. To protect yourself against a potential spammer, hacker or cyber criminal Dyn offers a way to display the a proxy server's information instead of your own personal information.
FatCow has one of the cheapest offers for an entire website package, with hosting and domain names for just thirty cents during your first month. After, that the price is $10.99 a month or $59.88 for the whole year, in a shared hosting package with enough bandwidth for most people. This is a limited promotion I found, but they still sell fairly well-priced packages (their "fat" options come with extras like marketing and advertising credits), and will gladly offer you perks for transferring your domains and hosting to them.
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.
