AI overview
A country code top-level domain is the final part of a website address that identifies a specific country or territory—for example, ".uk" for the United Kingdom or ".jp" for Japan. These domains matter because they help organize the internet geographically and let people know where a website is associated with, though they can also be used creatively by anyone, regardless of location.

A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, [territory] identified with a country code. All ASCII ccTLD identifiers are two letters long, and all top-level domains are ccTLDs.
In 2018, the Internet Assigned Numbers Authority (IANA) began implementing internationalized country code top-level domains, consisting of language-native characters when displayed in an end-user application. Creation and delegation of ccTLDs is described in RFC 1591, corresponding to ISO 3166-1 alpha-2 country codes. While gTLDs have to obey international regulations, ccTLDs are subjected to requirements that are determined by each country’s domain name regulation corporation. With over 150 million domain name registrations today or as of 2022, ccTLDs make up about 40% of the total domain name industry.
