Domain name extensionWhen you choose a domain name, one of your choices will be what domain extension or Top Level Domain (TLD) extension to use. There are hundreds of top-level domains from which to choose. Here is the breakdown of the most popular ones.
- The original top level domains (TLDs) include: .com, .net, .org, .int, .gov, .edu, and .mil. Only some of them are available for general use, and .com is far and away the most important.
- Many country code top level domains (ccTLDs) exist, including: .au (Australia), .cn (China), .in (India), .jp (Japan), .ph (Philippines), and .uk (United Kingdom).
- There are also topic specific generic top level domains (gTLDs), though their use has yet to catch on widely, including: .accountants, .agency, .business, .city, .digital, .photography, and .social.
