.zero domain availability and monitoring
Look up any .zero name to see if it is registered, who runs it, and when it expires. Add it to your watchlist and we check it again every night.
How we check .zero domains
We query the registry's own RDAP service at https://rdap.identitydigital.services/rdap, the protocol that replaced WHOIS. Answers come straight from the source, so an available result means the registry itself has no record of the name.

Waiting for a .zero name?
Add the domain to your watchlist and Domain Sentinel checks it every night. You get an email the moment it becomes available, expires, or changes hands.
