Check if a .io domain name is available
Type a name to instantly see whether the .io domain is free (from ~€38 for the first year). Nomok also checks 70 other platforms at once: other extensions, social networks and the company register.
How Nomok checks .io
The .io registry has no public RDAP server, so Nomok relies on DNS. A domain with name servers is "taken"; without name servers it is "likely available", to be confirmed at the registrar.
Good to know
A domain name has 1 to 63 characters (letters, numbers, hyphens, not at the start or end). .io is open to everyone, with no residency requirement.

How do I know if a name is available on .io?

Is the check free?
Yes, with no sign-up and no reasonable limit. Searched names are not stored.
