What is a top-level domain (TLD)?
A top-level domain (TLD) is the part of the domain name located to the right
of the dot (" . "). The most common top-level domains are .com, .net, and
.org. Some other popular top-level domains are .biz, .info, .name, and .ws.
These common top-level domains have certain guidelines attached, but are for
the most part available to any registrant, anywhere in the world.
There are also restricted top-level domains (rTLDs), like .aero, .biz, .edu,
.mil, .museum, .name, and .pro, that require the registrant to represent a
certain type of entity, or to belong to a certain community. For example,
the .name TLD is reserved for individuals and .edu is reserved for
Country-code TLDs (ccTLDs) are for Web sites and registrants of a particular
geographic location. For example: bz (Belize), .ca (Canada), .dk (Denmark),
.ec (Ecuador), ie (Republic of Ireland), .uk (United Kingdom), .us (United
States), and .zw (Zimbabwe).
