Check domain availability

Our tool checks domain availability by doing a DNS query to get domain name 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.

Frequently asked questions

How do I search for a domain name?

Search for a domain name by typing in our instant search box. We check available domain names as you type. If your domain is taken, we generate available domain names and extensions you can register.

How do I find out if a domain name is available?

A domain name search can tell you if a domain is available. Use our instant search tool to see if a domain name has already been registered by someone else. The tool checks many different extensions at once and shows other available domains on the same screen.

Which is the best domain extension?

.com is the best domain extension. It is so popular that can be hard to find an available .com domain you can register. About 150 million .com domain names are currently registered.

What is a domain name?
