PUBLIC DATA. ONE SIMPLE LOOKUP.How the domain availability check works
Every registered domain is recorded by its registry. We first ask public DNS whether the name exists: if it has nameservers, it’s taken. If it doesn’t, we ask the registry directly through RDAP, the official replacement for WHOIS. A “not found” answer there means the domain is almost certainly available.
A few registries, including .io, .co, .me, .de, .eu, and .us, don’t offer a public RDAP lookup. For those we can only confirm that the name isn’t in DNS, so we mark it “probably available” for you to confirm at a registrar.
Common questions
Is this domain available?
Type the name above. Green means the registry has no record of it, so you can usually register it straight away at any registrar. Red means it’s already registered; use the WHOIS link to see who it’s registered with and when it expires.
Can searching here let someone register my idea first?
No. The check runs in your browser and goes straight to public DNS and the registries. WhoHostsIt never sees, logs, or sells the names you search for.
What does “probably available” mean?
The name isn’t in DNS, but its registry has no public lookup to confirm it. Most of these names are free, but a few may be registered without nameservers, reserved, or on hold.
Why does an available domain cost more than usual?
Registries class some short or popular names as premium and set a higher price for them. We can’t see premium prices; the registrar shows the real price before you pay.
