Going beyond BGP ! To tell two networks apart in measurements, we need to trace to a target in each of them ! Finding networks via pure random scanning within BGP-announced prefixes doesn’t scale ! Start with BGP, add more information ! Small amounts of randomness ! Registration information (WHOIS) ! Information gathered in earlier scans
