What does the part after the final dot mean?

The part after the final dot is the top-level domain, or TLD. It helps identify the domain’s place in the naming system and the relevant registry, but it does not establish location, ownership or responsibility.

Examples include .com, .org, .uk and .online.

Generic and country-code endings

Some TLDs are generic, such as .com or .net. Others are country or territory codes, such as .uk, .fr or .au.

The ending does not automatically show:

  • where the website is hosted;
  • where the operator is located;
  • where the activity occurred; or
  • which person controls the service.

A .uk domain may be operated abroad, and a .com service may be hosted anywhere.

Identifying the registered domain

The TLD can help identify the relevant registry and the correct registrable domain.

In shop.example.co.uk, the registered domain is usually example.co.uk, not merely co.uk. Structures vary, so do not assume the last two labels always form the registered domain.

Record the address exactly

Be alert to lookalike endings, substituted characters and extra words designed to create a misleading impression.

Do not silently correct an unfamiliar spelling or replace an unusual ending with a familiar one in your notes.

Key takeaway

The TLD may guide registration enquiries and help identify the correct domain. It does not, by itself, prove where the service is located or who controls it.
