From Caribbean island to AI address
.ai is the country-code top-level domain for Anguilla, a small British Overseas Territory in the eastern Caribbean. For most of its life it was a quiet ccTLD. Then the AI boom hit, and suddenly every startup wanted a name that ended in the two letters investors were looking for.
Registrations climbed steeply after 2022, and the money flowing to Anguilla's government from .ai fees became big enough to matter in the island's budget — one of the most striking examples of a country earning real income from its two letters.
Who runs it
The Government of Anguilla is the TLD manager. As demand grew, the island brought in a large commercial registry operator to handle the technical side, while keeping control of the domain and its revenue.
Before you buy
Expect higher prices than .com, and check the minimum term — .ai has long required registrations of more than one year. Look up the name's history too: in a hot market, plenty of .ai names change hands, and you want one without a spammy past.
Good for
- AI products, agents, model labs and data companies
- Short brandable names with an obvious "AI" story
- Product sub-brands (yourbrand.ai alongside yourbrand.com)
Watch out for
- Prices are higher than .com, and premium names are common
- The registry has historically required multi-year registrations
- Hype cycles move — make sure the name still works if "AI" stops being the headline
.ai by the numbers
If a website ends in .ai, it lives under the country-code domain of Anguilla, a territory in Caribbean.
Outside Anguilla, plenty of people know .ai for a different reason: it reads as artificial intelligence. That second meaning doesn't change who's in charge, though. The domain still belongs to Anguilla, and its registry sets the rules.
A little context on Anguilla: the capital is The Valley, the main language is English, the currency is the Eastern Caribbean dollar (XCD) and the international dialing code is +1264.
IANA lists Government of Anguilla as the manager of .ai, with an address in Anguilla. The registry's website is https://nic.ai. ccTLD managers set their own policies — who can register, which second-level names exist, pricing to registrars — so those rules differ from country to country.
Under the hood, the root zone points to 6 name servers for .ai, every one of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .ai haven't been tampered with on the way. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.ai).
.ai vs other endings
.ai FAQ
What country is .ai?
Anguilla, a British Overseas Territory in the Caribbean. "AI" is its ISO 3166-1 code.
Why are .ai domains so expensive?
Anguilla sets the wholesale price, demand from AI companies is intense, and registrations have traditionally required a multi-year minimum term, so the up-front cost is higher than a one-year .com.
Who benefits from .ai sales?
The Government of Anguilla. Fees from .ai registrations have become a significant source of public revenue for the island.
What does .ai mean?
Officially, .ai is simply the ISO 3166-1 code for Anguilla. Online, it's also used for artificial intelligence — a "domain hack" that uses the letters for what they spell.
What does .ai mean in an email address?
Only that the sender's domain is registered under .ai. Because .ai is also used for artificial intelligence, it doesn't necessarily mean the person is in Anguilla.
Who owns the .ai domain?
IANA lists Government of Anguilla as the manager of .ai: it runs the registry and sets the rules for Anguilla's ccTLD. Individual .ai names belong to whoever registers them.
Can I register a .ai domain from the US?
It depends on Government of Anguilla's policy. Some ccTLDs are open to anyone in the world, while others require a local address, company or trademark. Check the registry (https://nic.ai) or an accredited registrar before you buy.
Is .ai DNSSEC-signed?
Yes. The root zone has a DS record for .ai, so DNSSEC validation works all the way down from the root.
How do I look up who owns a .ai domain?
Query the registry's registration data service: the WHOIS server is whois.nic.ai, and RDAP lookups go to https://rdap.identitydigital.services/rdap/. Many registrants use privacy services, so personal details may be hidden.
