Instant Domain Search®

Domain name search — check domain availability instantly

Domain name search results appear instantly as you type. It is hard to find an available domain because over one hundred million names are already registered. Great domain names 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. Good luck!

Domain extensions

Search .com and other extensions like .app, .dev, .store, and over a hundred more. We also search country-code domains (ccTLDs) like .ca,, .us, and .in. The domain name extensions page shows gTLD domain availability in a grid to make it easier to see many results at once.

Domain name generator

Our domain name generator adds thousands of popular beginnings and endings to your domain name search to find available names for registration. Use the generator to find website names for your new business or online store.

Domains for sale

Search millions of domain names for sale. We work with large marketplaces like AfterNic, GoDaddy, and Sedo. AI-powered search helps find great names related to your domain name.

Expired domain names

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.

Private and secure

All traffic to the site is encrypted. Domain name search results are not recorded. Press Return to register your domain name. We use Google Analytics, which uses cookies, to see how you use this website over time.

Domain name availability

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

Green results mean the domain name is available!

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