WHOIS / RDAP
WHOIS / RDAP checker for domain registration data
The DataHouse WHOIS tool uses RDAP to read public domain registration data, registrar information, status values, important dates and nameserver data when exposed by the registry.
Dates
Review registration, update and expiration dates where the registry exposes them.
Nameservers
Compare public registration nameservers with DNS delegation results.
When should RDAP be checked?
- Before DNS, registrar or ownership changes.
- After domain migration or registrar transfer.
- When nameserver data differs from what administrators expect.
- During incident response involving a domain.
- Together with DNS, SSL and mail checks.
How to use RDAP data
RDAP is queried first. If a TLD does not expose a usable RDAP endpoint, the tool reports that limitation instead of pretending to have complete registration data.
FAQ: WHOIS / RDAP
Does WHOIS use RDAP first?
Yes. The tool uses RDAP through the endpoint indicated by IANA when it is available for the TLD.
