Find your new favorite IO domain

The going definition of nerd-cool.

One of our TLD favorites! The .IO domain extension is hugely popular amongst geeks, developers and internet startups. Ever wondered where .IO domains come from? It's the country code top-level domain (ccTLD) of the British Indian Ocean Territory, a small uninhabited island situated between Africa and Indonesia. So if you always wanted to have an exotic and unique domain name, you should purchase your own .IO domain today.

.IO can stand for Input/Output and is often used for domain hacks such as or You could also register a .IO web address if you are an alien from Jupiter's moon Io, but we highly doubt this is the case. However, please let us know if you are visiting our website from outer space and we will enable SpacePal payments as an alternative payment method for your account.

Your domain registration questions, answered

How does getting a domain work?

There are two pieces to this equation. First, there are domain registries that own the individual top-level domains (like Verisign, which owns .com, .net, and a few other TLDs). Then there's us, the domain registrar, which provides a big online store that houses all the TLDs in one convenient location. When you register a domain, we reserve it for you through the individual registries... like an Amazon of sorts if you were looking for an HDMI cable.

Are there any additional things I need to buy?

Nope, every domain we sell comes with all the bells and whistles attached. If the TLD supports WHOIS privacy, we turn it on automatically. If you want to transfer your domain to another registrar, we don't have any secret add-ons to keep you tied down. And we don't place any weird ads or parking pages on unused domains — we don't see that much anymore, but it was a thing companies have done in the past.
