Domain Name Search

Domain name search results appear instantly as you type. Our domain checker automatically generates available domain names, finds aftermarket (taken) domains for sale, and checks domain availability for popular domain extensions instantly! Great domains are short, memorable, and easy to spell.

Try not to use hyphens or numbers. A good place to start is what someone might type into a search engine to find your website or online store. When you find your perfect domain name, we link you to our sponsor partners so you can buy it before it’s gone.

Expired domains

Search domain names that are about to expire. Some registrars let you buy the domain name immediately, sometimes the names go to an auction, and others will backorder the name for you.

Domain extensions

Search .com and other domain extensions like .app, .dev, .store, and over a hundred more. We also search country-code domains (ccTLDs) like .ca,, .us, and .in.

Check domain availability

Instant Domain Search 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 that the domain name is taken. Do a WHOIS lookup to see when the current registration expires.

Green results mean the domain name is available to register!

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