Reserved Names

All registry operators are required by their Registry Agreement (RA) to exclude certain domain names from registration in a Top Level Domain (TLD). These reserved names include strings that are for Country Code Top Level Domains (ccTLDs), ICANN-related names (such as ICANN), IANA-related names (such as example), country and territory names, international and intergovernmental organizations, and names that the registry operator can use in connection with the operation of the TLD.
