Free whois lookup

yWhois is a free whois lookup service that allows you to check the registration details of a domain name, autonomous system number (ASN), or IP address using RDAP, or "Registration Data Access Protocol."

Your IP address is 3.149.239.70

yWhois should automatically detect whether you're looking up a domain name, ASN, or IP address. If this doesn't seem to be working correctly, you may be inputting characters besides the domain, ASN, or IP you're looking for.

Subdomains are not supported! IP blocks are not supported - you must input a single IP address!

What domain name extensions/TLDs are supported?

Most common domains are supported at this time. To view a complete list of supported domains, click here. As this tool uses the newer RDAP standard, if the domain registry for a particular TLD doesn't support RDAP, or requires authentication, we can't get data from it. Apparently, by the end of 2025 all registries will support RDAP, but we'll see if that actually happens.

Why is it called yWhois?

y not?
