Domain Name

Term · Environment · MLC-T-ENV-008406

1. A domain name locates an organization or other entity on the Internet. For example, the domain name www.epa.gov locates an Internet address for "epa.gov" at Internet point 199.0.0.2 and a particular host server named "www". The "gov" part of the domain name reflects the purpose of the organization or entity (in this example, "government") and is called the top-level domain name. The "epa" part of the domain name defines the organization or entity and together with the top-level is called the second-level domain name. The second-level domain name maps to and can be thought of as the "readable" version of the Internet address. A third level can be defined to identify a particular host server at the Internet address. In our example, "www" is the name of the server that handles Internet requests. (A second server might be called "www2".) A third level of domain name is not required. For example, the fully-qualified domain name could have been "totalbaseball.com" and the server assumed. Subdomain levels can be used. For example, you could have "www.water.epa.gov". Together, "www.epa.gov" constitutes a fully-qualified domain name.
