Check domain availability

Our tool checks domain availability by doing a DNS query to get search results as fast as possible. WHOIS domain lookups are much slower than DNS queries, but provide more information about who registered the name.

Red results mean the name is taken. Do a WHOIS lookup to see when the current registration expires.

Green results mean the name is available and you can register with one of our partners!

Blue results show names for sale. Buy them from one of our auction partners.
