A combination of letters and numbers that locates an entity or an individual on the Internet. For example, the domain name www.eurodns.com locates an Internet address for "eurodns.com" at the Internet Protocol address 126.96.36.199 and a specific host server named "www".
A domain name usually consists of three parts: the "top-level" domain - usually called extension or "TLD"- that can be for example geographic (country code TLD = ccTLD, for example .de for Germany) or generic (general TLD = gTLD, for example .com for commercial entities). the second level domain "eurodns" in our example, identifies the organization, site or individual; the third level which identifies a particular host server at the Internet Point. In our example, "www" is the name of the server that handles Internet requests. (Another server could have been called "www2".)
