Every domain name ends in a top-level domain (TLD) name, which is always either one of a small list of generic names (three or more characters), or a two-character territory code based on ISO-3166 (there are few exceptions and new codes are integrated case by case). Top-level domains are sometimes also called first-level domains.

The generic top-level domain (gTLD) extensions are:

Generic   .biz · .com · .info · .name · .net · .org · .pro
Sponsored   .aero · .asia · .cat · .coop · .edu · .gov · .int · .jobs · .mil · .mobi · .museum · .tel · .travel
Infrastructure   .arpa
Deleted/retired   .nato
Reserved   .example · .invalid · .localhost · .test
Pseudo   .bitnet · .csnet · .local · .root · .uucp · .onion · .exit
