Domain Lookup

Smart lookup combining RDAP and Whois.

How does it work?

The Domain Lookup tool is a smart resolver in an era where domain data is fragmented between legacy WHOIS and modern RDAP protocols. It determines the best source by first checking for RDAP support, then falling back to traditional WHOIS. Regardless of the underlying protocol, it returns consistently structured and formatted data.
