Could riswhois generate statistics of "parent routes" for given route? [ parent, not ancestor] My goal is achieve better coverage of IP->AS mappings based on riswhois provided data. Unanimous AS reports (after ignoring default route) give very good starting point I would like to extend. For 65.54.160.0/19 I would like to know how many of 58 rispeers reporting the route reports also 65.52.0.0/14 route as belonging to AS8070. e.g. route: 65.54.160.0/19 origin: AS12076 [...] num-rispeers: 58 numrp-parent: 58 65.54.160.0/19 AS8070 P.S. As security precaution riwhois may limit number of parent routes reported to e.g. <10 ---------------------------------------------------------- $whois -h riswhois.ripe.net -- 65.54.162.200 [leading comments and default route entry skipped] route: 65.52.0.0/14 origin: AS8070 descr: MICROSOFT-CORP---MSN-AS-BLOCK - Microsoft Corp lastupd-frst: 2005-07-21 08:28Z 202.12.28.190@rrc00 lastupd-last: 2005-09-05 07:49Z 193.111.172.55@rrc03 seen-at: rrc00,rrc01,rrc03,rrc04,rrc05,rrc06,rrc07,rrc10,rrc11,rrc12,rrc13,rrc14 num-rispeers: 58 source: RISWHOIS route: 65.54.160.0/19 origin: AS12076 descr: HOTMAIL-AS - Hotmail Corporation lastupd-frst: 2005-06-29 08:05Z 195.66.224.151@rrc01 lastupd-last: 2005-09-05 07:49Z 193.111.172.55@rrc03 seen-at: rrc00,rrc01,rrc03,rrc04,rrc05,rrc06,rrc07,rrc10,rrc11,rrc12,rrc13,rrc14 num-rispeers: 58 source: RISWHOIS ---------------------------------------------------------- -- Andrzej [en:Andrew] Adam Filip anfi@priv.onet.pl anfi@xl.wp.pl All that is necessary for the triumph of evil is that good men do nothing -- Edmund Burke (1729-1797)
