The domain name is the same as an IP address (which represents a physical point on the Internet), except the domain name is letters and numbers that make sense to people, while the IP address is a series of numbers. Thus, a domain name more easily locates an organization or other entity on the Internet. When someone types a domain name into a Web browser, the requested Web page opens. For example, the domain name www.yourdomain.com locates an Internet address for "yourdomain.com."

A domain name consists of a top-level and a second-level domain. The "com" part of the domain name generally reflects the type or purpose of the organization or entity and is called the top-level domain (TLD) name. The part of the domain name located to the left of the dot (".") – "yourdomain" in this case – is called the second-level domain (SLD) name. The second-level domain name – the "readable" part of the address – refers to the organization or entity behind the Internet address. Second-level domains must be registered through an ICANN (Internet Corporation For Assigned Names and Numbers) accredited registrar.

The Internet domain name system (DNS) consists of a directory of all the domain names (and their corresponding computers) registered to particular companies and persons using the Internet. DNS applies to domains that are registered and hosted. If the registrant elects to, a domain can instead be registered and parked. A parked domain name does not need a DNS affiliation.
