NANOG Meeting Presentation Abstract

Who are the Anycasters?
Meeting:	NANOG59
Date / Time:	2013-10-09 11:30am - 12:00pm
Room:	Akimel Ballroom 3 & 4
Presenters:	Speakers: Jim Cowie, Renesys.
Abstract:	In this talk, we describe two techniques which employ traceroutes and BGP data to identify which prefixes in the global routing table are "anycasted", or put more precisely, are announced from more than one place on Earth. Having identified several hundred prefixes, we take a look at which ASNs announce the most anycasted prefixes and what are some interesting anycasted prefixes. Many of the same techniques used to study BGP route hijacks also expose interesting data about legitimately anycasted prefixes.
