From Wikipedia, the free encyclopedia

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]

IANA distinguishes the following groups of top-level domains:[5]

Original top-level domains

Summarize
Perspective

Seven generic top-level domains were created early in the development of the Internet, prior to predate the creation of ICANN in 1998.

Country code top-level domains

As of 20 May 2017, there were 255 country-code top-level domains, purely in the Latin alphabet, using two-character codes. As of June 2022, the number was 316, with the addition of internationalized domains.[1]

Proposed internationalized ccTLDs

Internationalized domain names have been proposed for Japan and Libya.

Internationalized generic top-level domains

Summarize

All of these TLDs are internationalized domain names (IDN) and support second-level IDNs.

Special-use domains

ICANN/IANA has created some special-use domain names which are meant for technical purposes. ICANN/IANA owns all of the special-use domain names.[168]

Non-IANA domains

Summarize
Perspective

Besides the TLDs managed (or at least tracked) by IANA or ICANN, other independent groups have created, or had attempted to create, their own TLDs with varying technical specifications, functions, and outcomes.

Internet Engineering Task Force proposals for local TLDs

The IETF has submitted several requests for comments on TLDs that could be used to represent local devices and services.

Blockchain-registered

Blockchain-based domains are registered and exchanged using a public blockchain like Ethereum. Oftentimes, these domains serve specific functions such as creating human-readable references to smart contract addresses used in DApps or personal wallet addresses.[174] Generally, these non-standard domains are unreachable through the normal DNS resolution process and instead require clients to use some sort of transparent web proxy or gateway to access them

Alternate roots

In the case of alternative DNS roots, organizations or projects make use of the same mechanisms of the DNS but instead take on the role of ICANN in managing and administering an entirely separate root zone, thus having the ability to create new TLDs independently. However, this doesn't make these domains any less isolated from the rest of the internet, though the ability for clients to resolve them theoretically only requires switching to a recursive DNS resolver that recognizes and serves records underneath the alternate root zone.
