To re-phrase what Tony and Marten have said: Queries received without a prefix length explicitly specified are treated as /32 queries, i.e. the default prefix length is /32. In general (and in this case) if there is no exact match for the queried address the search algorithm finds the entries with the first (longest) less specific address. This is backward compatible for classful entires. This search algorithm is repeated *per source*. The consequence is that depending on the source the first less specific can have a different prefix length. Unfortunately we can not think of a more sensible behavior. > foo-selina:/u/selina: ra 192.5.4 > route: 192.5.4.0/23 > descr: Vixie Enterprises > descr: 116 Stanley Street > descr: Redwood City > descr: CA 94062, USA > origin: AS3557 > comm-list: COMM_NSFNET > advisory: AS690 1:3561(11) 2:3561(218) 4:200(144) 5:701(147) > mnt-by: MAINT-AS3557 > changed: nsfnet-admin at merit.edu 950118 > source: RADB > > route: 192.5.4.0/23 > descr: NET-VIX2 > origin: AS3557 > advisory: AS690 1:3561(11) 2:3561(144) 3:3561(27) 4:3561(147) 5:3561(218) 5:701(147) 6:7 > 01(134) > mnt-by: BARRNET > changed: vaf at valinor.barrnet.net 950111 > source: MCI Search for 192.5.4.0/32 in RADB found 192.5.4.0/23.

This raises the valid question whether 192.5.5.0/24 is indeed still supposed to be announced. > > bugsy-sfp:/u/sfp: whois -h whois.ra.net 194.128 > > route: 194.128.0.0/15 > > descr: PIPEX-BLOCK3 > > origin: AS1849 > > advisory: AS690 1:1849 2:701(147) 3:701(134) 4:1800 > > remarks: Holes to come! > > mnt-by: AS1849-MNT > > changed: tim at pipex.net 950428 > > source: RIPE > > > > bugsy-sfp:/u/sfp: whois -h whois.ra.net 194.128/15 > > route: 194.128.0.0/15 > > descr: PIPEX Ltd > > descr: 216 Cambridge Science Park > > descr: Milton Road > > descr: Cambridge > > descr: England > > descr: CB4 4WA > > descr: UNITED KINGDOM > > origin: AS1849 > > comm-list: COMM_NSFNET > > advisory: AS690 1:1849 2:701(147) 4:1800 > > mnt-by: MAINT-AS1849 > > changed: support at pipex.net 950511 > > source: RADB > > > > route: 194.128.0.0/15 > > descr: PIPEX-BLOCK3 > > origin: AS1849 > > advisory: AS690 1:1849 2:701(147) 3:701(134) 4:1800 > > remarks: Holes to come! > > mnt-by: AS1849-MNT > > changed: tim at pipex.net 950428 > > source: RIPE Sorry, I cannot reproduce that one at all. Everytime I do it the answer is the second one, as it should be. Daniel -------- Logged at Thu Jun 1 09:48:47 MET DST 1995 ---------
