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. IANA also oversees the approval process for new proposed top-level domains for ICANN.

, the IANA root database includes 1593 TLDs. This database also includes 156 that are not assigned (revoked or retired) and 11 test domains, nor in the root.zone file (the file also includes one root domain).

This number of active TLDs has decreased from 1502 in March 2021, reflecting removals, retirements, and changes in the root zone database.

Types

IANA distinguishes the following groups of top-level domains:

  • infrastructure top-level domain (ARPA)
  • generic top-level domains (gTLD)
  • generic-restricted top-level domains (grTLD)
  • sponsored top-level domains (sTLD)
  • country code top-level domains (ccTLD)
  • test top-level domains (tTLD)

Original top-level domains

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

  • Name: DNS names
  • Entity: intended use
  • Administrator: managers
  • Notes: general remarks
  • IDN: support for internationalized domain names (IDN)
  • DNSSEC: presence of DS records for Domain Name System Security Extensions

|- valign="top"

| .com || Commercial ||Verisign

| This is an open TLD; any person or entity is permitted to register. Though originally intended for use by for-profit business entities, for a number of reasons it became the main TLD for domain names and is currently used by all types of entities including nonprofits, schools, and private individuals. Domain name registrations may be successfully challenged if the holder cannot prove an outside relation justifying reservation of the name, to prevent "squatting". It was originally administered by the United States Department of Defense.|| || || ||

|- valign="top"

| .org || Organization || Public Interest Registry ||This is an open TLD; any person or entity is permitted to register. Originally created as a miscellaneous category as stated in RFC 920 (October 1984) "...any other domains meeting the second level requirements," and clarified in RFC 1591 (March 1994), "This domain is intended as the miscellaneous TLD for organizations that didn't fit anywhere else. Some non-government organizations may fit here." While mainly non-profits have used this domain, it was never restricted from miscellaneous use.|| || || ||

|- valign="top"

| .net || Network ||Verisign

| This is an open TLD; any person or entity is permitted to register. According to RFC 1591 (March 1994) "This domain is intended to hold only the computers of network providers."|| || || ||

|- valign="top"

| .int || International|| Internet Assigned Numbers Authority || The .int TLD is strictly limited to organizations, offices, and programs endorsed by a treaty between two or more nations. However, a few grandfathered domains do not meet these criteria. || || || ||

|- valign="top"

| .edu|| Education || Educause (via Verisign)|| The .edu TLD is limited to specific higher educational institutions such as, but not limited to, trade schools and universities. In the U.S., its use was restricted in 2001 to post-secondary institutions accredited by an agency on the list of nationally recognized accrediting agencies. This domain is therefore almost exclusively used by colleges and universities. Some institutions, such as the Exploratorium, that do not meet the current registration criteria have grandfathered domain names.|| || || ||

|- valign="top"

| .gov || U.S. national and state government agencies || Cybersecurity and Infrastructure Security Agency (via Verisign) || The .gov TLD is limited to United States governmental entities and agencies as well as qualifying state, county and local municipal government agencies, and tribal governments.|| || || ||

|- valign="top"

| .mil || U.S. military || United States Department of Defense || The .mil TLD is restricted to departments, services and agencies of the United States Department of Defense. || || || ||

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. , the number was 316, with the addition of internationalized domains. || (Cancelled) || ||

Special-use domains

Non-IANA domains

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.

Microsoft Windows

Within Microsoft Windows there are some special purpose domain names that partially conflict with publicly assigned ones.

| A special-use domain primarily for representing IPv6 addresses in UNC paths as ":" is a reserved character in Windows. Usage is not restricted to UNC paths. Compared to ip6.arpa reverse lookup domains it will return an IPv6 address but without generating any DNS queries.

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. 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

{|class="wikitable sortable"

|- style="background:#a0d0ff;"

!Name

!class="unsortable"|Notes

|-

|.agt

|Polygon

|The .agt (agent) TLD is a decentralized top-level domain operating within the Web3 ecosystem, primarily positioned as an identifier for AI agents and autonomous systems. The TLD is offered by Web3 domain providers, such as Freename, an ICANN-accredited registrar that bridges traditional DNS with blockchain technology. .agt domains can be minted as NFTs across multiple blockchains (Polygon, Solana, BNBChain, BASE, Aurora, Sei, Abstract, Chiliz, and Etherlink), eliminating traditional renewal fees and providing registrants lifetime ownership. Popular .agt domains function as human-readable aliases for AI agents, agentic and tool-calling functions, cryptocurrency wallets, decentralized digital identities, AI agent ID, and addresses for hosting decentralized websites.

|-

|

|Handshake

|Handshake is both an alternative DNS root zone and a domain name-centric blockchain meant for managing TLDs in a decentralized way which allows virtually any domain to be registered as a TLD by end users. The project intends to be a more resilient and distributed implementation of the global root zone without needing a centralized organization, like ICANN, to manage or operate it. However, it doesn't aim to outright replace the existing root zone, as it reserves all existing TLDs so that a query for wikipedia.org, for example, that is sent to a Handshake node can be redirected to the traditional root.

|- valign="top"

| .eth|| Ethereum

|Domains under the .eth TLD are primarily used as human-readable aliases to Ethereum wallet addresses, rather than IP addresses, though some efforts into expanding the use of .eth into the traditional DNS space have been made.

|- valign="top"

| .crypto || Ethereum

|.crypto aims to make cryptocurrency wallet address resolution easier, with the exception that, unlike the other examples mentioned here, the TLD is the product of a for-profit company, Unstoppable Domains, that markets the domain as an alternative DNS root despite being entirely dependent on the traditional root zone.

|- valign="top"

| .bit|| Namecoin

|Namecoin's .bit TLD technically operates as a single-domain DNS root, though has historically peered with the OpenNIC root zone to provide greater accessibility. The popularity and usage of .bit domains is much lower than the other projects mentioned, despite it being the earliest example. This is primarily due to the negative reputation Namecoin has garnered after .bit domains became popular for sharing and distributing illegal or illicit content such as malware, which ultimately prompted OpenNIC to end its peering agreement and stop serving the TLD in its root zone in 2018.

|}

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, as 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.
