WHOIS Lookup

WHOIS and RDAP, briefly
Every domain ending has one registry, which keeps the list of names registered under it: who sells each one (its registrar), when it was registered and when it expires, its status and its nameservers.
RDAP is how a registry answers that question today, in a form a program can read. We find each ending's registry in IANA's own list and ask it directly. Where an ending has no RDAP yet, we ask its older WHOIS server instead and show its answer as it sent it.
Who owns a name is usually private now. Registries and registrars withhold the owner's details by law, and this page says so rather than guessing.
Questions about this tool
Where does this information come from?
From the registry of the domain's ending itself. We look its address up in IANA's list of registries and ask it with RDAP, or with WHOIS where an ending has no RDAP. We keep an answer for up to an hour, and the page says when it was checked.
Why is the owner's name hidden?
Since 2018 most registries and registrars no longer publish a private person's name, email or address, under privacy law and the rules of ICANN. The details still exist and the registrar can be asked for them for a lawful reason, but they are not public, so we cannot show them.
What does "transfer locked" mean?
The status clientTransferProhibited means the name cannot be moved to another registrar until its owner removes the lock at their current registrar. Most registrars lock names this way by default, to stop them being moved without the owner knowing.
Why does a .bd domain show no record?
The .bd registry offers no RDAP or WHOIS service: IANA lists neither for it, and the same goes for .com.bd and the other endings under .bd. No lookup tool like this one can ask about these names, so we say so plainly. The registry itself is the place to ask.
Does "not registered" mean I can buy the name?
It means the registry itself said it holds no registration for that name. Most such names can be registered, but a registry may also hold names back or sell some at a premium, which an order shows. Search for it on our domains page to see its price.
