Top-level Domains

    The ending of the domain name (top-level) tells you what type of site the domain should be. The part before the ending is called the second-level, and this is what you may register (for .com, .org, or .net) if you wish to establish a unique web address. Sometimes another name precedes the second level domain to identify a particular server for the organization, such as icampus.mit.edu  A registrant must verify identity to register a .gov, .mil, or .edu second level domain.  Following are common top-level domains (TLD) and what they stand for:

Six common higher level domains:

com - commercial
org - non-profit organization 
gov - U. S. government 
net - network service
mil - U.S. military
edu - education (4-year college) 

Geographical domains include:

us - United States
ca - Canada
jp - Japan
uk - United Kingdom
