Whois-compatible framework for disclosing routing data

The Prefix WhoIs Project provides a whois-compatible client and server framework for disclosing various up-to-date routing information. Instead of using registrar-originated network information (which is often unspecific or inaccurate), Prefix WhoIs uses the Internet's global routing table as gleaned from a number of routing peers around the world. Other sources of information, such as imported data from ARIN are also supported (a separate agreement with ARIN is required).
