A domain name locates an organization or other entity on the Internet. For example, the domain name “www.sans.org” locates an Internet address for “sans.org” at Internet point 199.0.0.2 and a particular host server named “www”. The “org” part of the domain name reflects the purpose of the organization or entity (in this example, “organization”) and is called the top-level domain name. The “sans” part of the domain name defines the organization or entity and together with the top-level is called the second-level domain name.
