C

  • country code top-level domainccTLD

    The class of top-level domains reserved for use by countries, territories, and geographical locations identified in the ISO 3166-1 Country Codes list.

    ccTLDs can base their names on the two-letter country codes defined by the ISO 3166-1 standard (e.g., .jp for Japan, .fr for France, .ke for Kenya), or they can represent a country or territory name in a script other than US-ASCII characters.

    Because ccTLDs are managed locally, the rules and policies for registering domain names vary across ccTLDs.
