ccTLD - Country Code Top Level Domain
Two letter domains, such as .it (Italy), .de (Germany) and .jp (Japan) (for example), are called country code top level domains (ccTLDs) and correspond to a country, territory, or other geographic location. The rules and policies for registering domain names in the ccTLDs vary significantly and ccTLD registries sometimes limit use of the ccTLD to citizens of the corresponding country or continent.
