Buy .ac domain – everything you need to know
Whether you're an individual, a business, or part of an academic institution, this page covers what you need to know about registering a .ac domain — from what the extension actually is, to how the process works at Site.eu.
Why choose a .ac domain and where to find a cheap .ac registration
The .ac domain is the country code top-level domain (ccTLD) for Ascension Island, though its use has spread well beyond that origin. It's particularly popular among academic institutions, research centres, and educational organisations — universities, colleges, schools, and e-learning platforms tend to find it a natural fit. That said, businesses in fields like accounting, acting, or access control may also find .ac a memorable and relevant choice for their brand.
A cheap .ac registration through Site.eu means you're not paying over the odds for any of that. We're consistently among the more affordable providers for this extension. And beyond pricing, we also offer web hosting, a website builder, and email services — all at competitive rates — so you can manage your online presence from one place without the usual hassle.
Check .ac domain availability with ease
Before registering, you'll want to check whether your preferred name is actually available. At Site.eu, we provide a straightforward domain checker that gives you availability results quickly. Just enter the name you have in mind and you'll see the .ac availability status right away — enough information to make a confident decision.

Features of the .ac domain extension
Registering a .ac domain through Site.eu gives you full control over how it's managed. You can update DNS records, modify nameservers, and change domain holder information as your needs evolve — useful as your technical setup or business grows over time.
Security and naming conventions
The .ac extension supports domain lock, which adds a layer of protection against unauthorised transfers or changes. On naming conventions, you have quite a bit of flexibility — domain names can be anywhere from 1 to 63 characters in length. One thing worth noting: .ac does not currently support Internationalized Domain Names (IDN), so names must be registered using standard ASCII characters only.
