gwhois is a generic whois client (and server) which strives to know the right server to query for each and every top level domain and IP address. You can ask gwhois about a domain or IP address, and it will automatically forward your query to the appropriate server. It even queries whois servers that can only be reached by a Web form, and outputs the results as text. It can be used as a client or as a relaying server, so you can use your normal whois client to ask gwhois.
