List of Internet top-level domains

This list of Internet top-level domains (TLD) contains top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet. A list of the top-level domains by the Internet Assigned Numbers Authority (IANA) is maintained at the Root Zone Database.[1] IANA also oversees the approval process for new proposed top-level domains for ICANN. As of April 2021, their root domain contains 1502 top-level domains.[2][3] As of March 2021, the IANA root database includes 1589 TLDs. That also includes 68 that are not assigned (revoked), 8 that are retired and 11 test domains.[1] Those are not represented in IANA's listing[2] and are not in root.zone file (root.zone file also includes one root domain).[4]
