Top-level domain ( TLD ) refers to the last segment of a domain name, or the part that follows immediately after the “dot” symbol. TLDs are mainly classified into two categories: generic TLDs and country-specific TLDs. Examples of some of the popular TLDs include .com, .org, .net, .gov, .biz and .edu.
What is a domain name extension?
A domain extension is the top-level part of the domain name ( TLD ), such as .com, or .net. A majority of sites use .com, making it easy to forget that at their inception, each domain extension had a specific intended purpose. Well, that rings true today, even though the lines have been somewhat blurred.
