What is a TLD (Top Level Domain)?

I occasionally get this question, as many technical people don’t fully understand it.

A TLD is ‘actually” the last section of a URL (owned by the domain registrars themselves).


  • .com
  • .net
  • .org
  • .us (and other 2 digit country codes)

You can find a full list of TLD’s here:

Various other TLD’s have been proposed through the years, here are a few common ones (that are in various states of approval or implementation):

  • .museum
  • .info
  • .xxx
  • .biz
  • .mobi
