About the Bulk Domain Checker
Shortlisted a few names? Paste them here – one per line, with or without an extension – and check them all at once. Names without an extension are checked on the extension you choose.
Lookups use DNS first and the registry’s RDAP service for names without name servers, with a small number of lookups per registry at a time so that registries are not overloaded. Filter the list to the names that look available, star your favourites and download everything as a CSV file. Visitors without an account can check 20 names at a time; with a free account, 50.
Frequently asked questions
How many names can I check?
Up to 20 at a time without an account and up to 50 with a free account.
Can I mix extensions?
Yes. Write each name with its extension (brand.com, brand.co.uk, brand.io). Names without one use the extension you selected.
Why are some results slower than others?
Registered names are found quickly in DNS. Unregistered names need a registry lookup, and each registry answers at its own speed.
