WHAT IS A .AC DOMAIN

.ac Domain: Ascension Island's Country Code Extension

.ac is the country code top-level domain of Ascension Island in the South Atlantic, and it entered the root zone on 19 December 1997. The island forms part of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory. The zone is run by Internet Computer Bureau Ltd, a company based in the United Kingdom that operates the registry under the trading name NIC.AC and runs the .io and .sh zones as well. Registration happens directly at the second level, on a first come, first served basis, and applications are processed in real time.

At the second level there is next to no eligibility test. The rules state that an applicant may reside in any legal jurisdiction, and the registry's own site says anyone, anywhere can register; no documents, local address or trustee are required, and individuals may register in their own name. Because the string "ac" is associated with higher education worldwide, the extension is marketed on that reading, yet the registry itself advises academic institutions on the same page to register elsewhere. So .ac carries an academic echo, not accreditation. Third-level names such as com.ac are reserved for island residents.

Two details are worth knowing before you order. The first is the state of short names: all 36 single-character names, meaning every letter of the alphabet and every digit, have been registered since bulk allocations in 1998 and 2003, and the two-character space is heavily taken, so set your expectations accordingly. The second is a technical precondition: the registry expects the name's name servers to be live at the moment the application is submitted, so prepare the DNS side before you register. See whether the name you want is free on the domain name search page.

The bar in a dispute is lower than under UDRP: .ac has its own dispute resolution policy, adopted on 1 June 2020, which applies a three-element test resembling the UDRP used by generic extensions. The difference sits in the last element: it is enough that the name was registered in bad faith or is being used in bad faith, whereas the UDRP requires both at once. In practice this means a name you took in good faith years ago can still be lost over a later use. Proceedings run before the WIPO Arbitration and Mediation Center alone, and the only order a panel may make is cancellation or transfer to the complainant. Factor that risk in for names close to a trademark.

.ac Domain Lifecycle

Domain lifecycle

The stages in order, from registration to release
Available Before registration
Active 1 - 10 years
Redemption 30 days
Pending delete 30 days
Available Open again

Domain Is Available (Available)

Open-ended

A .ac address at this stage has not been taken yet, and it goes to whoever registers first. Check the name you have in mind — if it is free, it can be yours within minutes.

Domain Is Active (Active Period)

1 - 10 years

Once registration is complete the domain is yours for the term you chose. You can renew at any point before expiry to keep it uninterrupted, or switch on auto-renewal so you never have to watch the date.

Redemption Period (Redemption Period)

30 days

The domain is not released the moment it expires — during this window it is still yours and can be recovered. Some extensions charge an extra restore fee at this stage, so renewing before expiry is always the cheaper route.

Pending Delete Period (Pending Delete Period)

30 days

If the redemption window is missed too, the domain enters the final stage and waits to be deleted. Renewal and recovery are no longer possible here; when the period ends the registration is removed for good.

Domain Is Available Again

Open-ended

Once deletion completes, the domain leaves the system and anyone can register it — popular names are often taken the same minute by someone watching. Keep auto-renewal on so a name you care about never gets this far.

Frequently Asked Questions About .ac Domains

The questions people actually ask before registering — answered plainly.

  • There is barely a requirement to speak of. For second-level names the rules state that an applicant may reside in any legal jurisdiction, so there is no country, sector, document or local representative condition. Individuals and companies register on identical terms, and no cap is placed on how many names one holder may take. Priority is purely chronological: the registry allocates on a first come, first served basis and explicitly warns applicants not to act in reliance on a name before it is actually entered in the register. The one technical precondition is that the name's name servers must be operating when the application is submitted.

  • To Ascension Island. The island lies in the South Atlantic between Africa and South America and forms part of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory. IANA's root zone record lists the manager of the extension at a Georgetown address on the island itself. The extension is sometimes confused with the Åland Islands; Åland's extension is .ax and has nothing to do with .ac. As a matter of contract law the zone points to England: the registration agreement is governed by English law and any action is brought in England.

  • No. The string "ac" is associated with higher education worldwide because many countries group their universities under a second-level "ac" label such as ac.uk or ac.jp. The registry sells that reading and presents the extension as a lasting address for students and teaching staff. On the very same page, however, it records its own advice: academic institutions are recommended to register in other top-level domains. So .ac carries an academic echo but conveys no accreditation, and nobody treats an institution as formally recognised because its address ends in .ac.

  • In one-year increments. The registry's terms state that the fee covers a period of one year for each new registration and one year for each renewal, and add that the fee is non-refundable; the same clause notes that permitted changes to the record during the covered period are included in that fee. Taking several years at once is possible, and long-dated registrations do exist in the zone. The registry publishes no upper limit, so the maximum term available to you is set by the options presented at checkout.

  • The name is not deleted straight away. Measurement shows that at expiry the registry first renews the record automatically and places the name in a holding state; complete the renewal at that stage and you keep the name. If payment does not follow, the name moves into a redemption stage where it can still be recovered. The registry publishes the day counts for none of these stages in any of its documents, so do not plan around a guessed calendar; completing the renewal before the expiry date is the only safe route. Keep the email address held by the registry current, because reminders go there.

  • The rules permit single-character names, but none are left on the market. The text says single-letter and numeric names are open for registration "in a controlled and equitable manner". Measurement shows the practical position: every letter of the alphabet and every digit, that is all 36 single-character names, are registered and are being renewed regularly. The letters were handed out in one bulk allocation and the digits in a separate one. The two-character space is heavily taken as well. The real floor you will meet is therefore two characters, while the ceiling is sixty-three characters.

  • The registry has its own dispute resolution policy, and it differs from the UDRP used by generic extensions. A complainant must prove three elements: that the name is identical or confusingly similar to a mark in which they hold rights, that the holder has no rights or legitimate interests in the name, and that the name was registered or is being used in bad faith. Where the UDRP requires both limbs of that last element, the .ac policy treats either one as sufficient. Complaints go to the WIPO Arbitration and Mediation Center alone, the complainant normally bears the fees, and the only available orders are cancellation or transfer.

  • Largely not. In the registry's public lookup only the holder's organisation, state or province and country code stay visible; the name, street address, city, postal code, telephone and email are returned redacted. Every field of the administrative and technical contacts is withheld entirely. The registry's own rules attribute this to United Kingdom privacy law. Access to the withheld data follows a separate procedure in which the requester must show a specific legitimate interest and a proper legal basis. You can see how your own record appears on the whois search page.

  • Transfers are possible, but locking is the default in this zone. Measurement shows that most .ac names are held under a registrar-level transfer lock, so the first step is to have your current provider release the lock and issue the authorisation code. Some names additionally sit under a registry-level lock service, and the lookup output states this plainly; in that case the lock comes off only through a separate request made via the registrar. The registry reserves the right to charge for transfers, modifications and deletions. You can start on the domain transfer page.
