Help & FAQ

What is WHOIS?

WHOIS is a protocol to query databases that store information about registered domain names, IP addresses, and ASNs — such as who owns them, when they expire, and who manages the nameservers.
What can I look up?

You can look up domain names (e.g. google.com), IPv4 & IPv6 addresses (e.g. 1.1.1.1), and Autonomous System Numbers (e.g. AS15169).
Why is data outdated?

Results are cached to keep responses fast. Click the Reload button on the result to force a fresh lookup from the upstream registry.
What is RDAP?

RDAP (Registration Data Access Protocol) is the modern successor to WHOIS. It returns structured JSON data and is used as a fallback when WHOIS servers are unavailable.
