The Prefix WhoIs Project demonstrates continued progress in January 2017

Layer Four Traceroute, WhoB, pWidget, and other Prefix WhoIs tools have been updated. The Prefix WhoIs Project provides a whois-compatible client and server framework for disclosing various up-to-date network routing information and is also the home of layer four traceroute (LFT) and other popular open-source network tools. 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.
