The Prefix WhoIs Project provides a whois-compatible client and server framework for disclosing various up-to-date routing information via a familiar whois interface. Instead of using registrar-originated information (which is often unspecific or inaccurate), it uses the Internet's global routing table as gleaned from a number of routing peers around the network. The software consists of a 'pWhoIsd' server that responds to queries using a variety of output formats including pWhoIs-native, Cymru, and RPSL, the 'pWhoIs-updatedb' agent that parses routing information bases (RIBs) from Internet routers and populates a relational database, and the 'WhoB' command-line whois client.
