A domain name consists of one or more labels, each of which is formed from the set of ASCII letters, digits, and hyphens (a-z, A-Z, 0-9, -), but not starting or ending with a hyphen. The labels are case-insensitive; for example, 'label' is equivalent to 'Label' or 'LABEL'. In the textual representation of a domain name, the labels are separated by a full stop (period).
Your domain name is how visitors easily find you online. It is often the first step in getting your website started because it is like establishing your website’s street address on the internet. If you did not have a domain name, you would have to give out your IP address to everyone who wanted to visit your website, which would get confusing and be easily forgotten.
There are organizations that are called registries that manage each TLD option. When you register domain names, you would first visit a domain registrar who would in turn check with the registry that manages that TLD to see if the domain is available. If the domain for the TLD you want discovers that it is in fact available, the registry adds it to their registry and gives you access to it. If the domain has already been registered by another user for that TLD, you will be shown during the domain registration process that the domain isn't available.

In order to register any domain, you must provide certain personal information that you may not wish to be publically searchable in the Whois database. Signing up for WhoisGuard is a great way to keep your registration data private. WhoisGuard acts as a "shield" for your searchable information, displaying the address, phone number, and email of the domain registrar (Namecheap, e.g.) instead of your own. Keep in mind that WhoisGuard is an optional security add-on that must be renewed separately when you renew your domain.
Many desirable domain names are already assigned and users must search for other acceptable names, using Web-based search features, or WHOIS and dig operating system tools. Many registrars have implemented domain name suggestion tools which search domain name databases and suggest available alternative domain names related to keywords provided by the user.
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]
Yes. We recommend buying not only your domain name with your favorite extension (eg. .com), but also additional, alternative domain extensions (eg. .net, .info, etc). The reason is simple. Having more than one domain extension strengthens your online identity, secures your brand name and improves your online presence. Buying more than one domain extension also protects you from your competitors registering your additional extensions and enticing away your customers.
"We were in the naming process for the project and we were gravitating around the name assemble. Problem is, most major domains are taken for any variation of that name. But then we stumbled upon an article about new TLDs available for the year. We found .HAUS and immediately knew it was perfect. It was great to keep that assemble base name and then mash it up with that modern design oriented term like .HAUS. The response has been great! It’s always nice to have a unique name to help you stand out from the crowd.”

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.
Don’t get discouraged in your domain name search if what you’re looking for is already taken. We have a couple of ways for dealing with such a situation. You can try our Domain Buy Service, where we negotiate acquiring the domain from its current owner. We also offer a Domain Backorder service, where you purchase a backorder credit to give you a chance to get the domain when it goes into auction.

Here, we need to understand what a website accomplishes and how it boosts your prospects of an effective business. You get a fully cleared domain name from the registrar. They will issue a “universal resource locator,” which is the link you have directing you to your website. This makes your domain important and uniquely yours. What you get with a network domain is your dedicated spot/business/store on the internet.

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.
The first step to starting your website is registering your domain name. Think of your domain name as a street address for your website. Without a domain name, you would have to tell customers to visit your website at a temporary url such as instead of yourwebsite.com. Get your own domain name to lend your site a professional look and establish your online brand!
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).[27][1] In 2013 the US government seized Liberty Reserve, citing 18 U.S.C. § 982(a)(1).[28]

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.,, which is the reverse DNS resolution domain name for the IP address of a loopback interface, or the localhost name.
Many registrars reserve the right to revoke your domain name for specific reasons, typically if you use the domain for illegal purposes or purposes deemed unacceptable (such as spamming). Many contracts contain a clause letting the registrar delete your domain name for no apparent reason. The implication, of course, is that the domain name is the registrar's, not yours.
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.
NameCheap offers domain names to individuals and businesses, including a wide range of new TLDs that can draw further attention to your particular business segment. They also have a user-friendly control panel for buying domain names as well as offer hosting and tools for building your website. I personally used them to transfer over 25 domain names at once, and it took a few days and about three clicks. They're my go-to processor for names I'm just looking to hold.
Getting a domain name involves registering the name you want with an organisation called ICANN through a domain name registrar. For example, if you choose a name like "example.com", you will have to go to a registrar, pay a registration fee that costs around US$10 to US$35 for that name. That will give you the right to the name for a year, and you will have to renew it annually for (usually) the same amount per annum.

Even when you register and pay for your domain name, you won't necessarily be able to use the name for several hours or even a few days. The domain must propagate, meaning that the official domain name registry must be updated with your website's Domain Name System information. That's something that occurs on the backend without any need of input from you.

If you are looking for a TLD other than those listed above, our DNS services support domains in almost every TLD, as long as the registry and your registrar will delegate the domain for our nameservers. Domain Transfers are a one-time fee, priced at the one (1) year rate for the appropriate Top Level Domain and include an automatic one-year extension of the domain's expiration upon completion of the transfer.
Keep in mind that these are the highest value cash only sales that have been reported to us in the past week. This column is meant to be an educational tool, not a complete list documenting ALL high value domain sales. Such a list is impossible to produce because many sales are kept private at the insistence of buyers, sellers or both. Our procedure for verifying the accuracy of domain sales reports is available here.

ICANN renewed Verisign’s .com contract, this time with an interesting new clause — the $6 cap previously placed on Verisign’s fee was removed, granting permission for Verisign to raise their fee by 7% each year from 2007 to 2010, bringing it to $7.85. The justification given by ICANN was “to allow market forces to determine prices”, which I don’t quite follow, but I’m no Keynes. They also point out, in subtler language, that it’s the US government’s job to worry about Verisign’s monopoly, which is, I guess, fair.

The character set allowed in the Domain Name System is based on ASCII and does not allow the representation of names and words of many languages in their native scripts or alphabets. ICANN approved the Internationalized domain name (IDNA) system, which maps Unicode strings used in application user interfaces into the valid DNS character set by an encoding called Punycode. For example, københavn.eu is mapped to xn--kbenhavn-54a.eu. Many registries have adopted IDNA.
