What is a TLD? (Top Level Domain)

The term TLD stands for Top Level Domain, and refers to the last portion of a domain name.  For example, the domain name EXAMPLE.COM is part of the .COM Top Level Domain and the domain EXAMPLE.ORG is part of the .ORG Top Level Domain.

Different TLDs are often separate from each other in certain ways, such as the case of Name Servers.  The Name Server NS1.EXAMPLE.COM can be used with all .COM domains, however in order to use it on a .ORG domain, the .COM Name Server must first be added to the .ORG TLD by your Domain Provider if it has not been done before.
