The 172.16 to 172.31 block is reserved in RFC1918 for private internets. The last address 209.149.111.17 belongs to a bellsouth block. It's a safe bet that libidomax.com is a bellsouth customer, or a customer of a bellsouth customer. Probably bellsouth and alternet are peering and using a private network between themselves. --Dean At 05:11 PM 10/14/98 -0400, Barry Shein wrote: > >The following traceroute seems to indicate, according to ARIN, that >someone is running routers for spammers in the IANA Reserved netspace? > >First a traceroute: > >>world% traceroute www.libidomax.com >>traceroute to www.libidomax.com (209.149.111.17), 30 hops max, 40 byte packets >> 1 Boston-STD-F.std.com (199.172.62.80) 17 ms 4 ms 4 ms >> 2 553.Hssi2-0.GW2.BOS1.ALTER.NET (157.130.10.129) 59 ms 107 ms 69 ms >> 3 124.ATM3-0.XR1.BOS1.ALTER.NET (146.188.176.250) 77 ms 54 ms 37 ms >> 4 191.ATM2-0.TR1.NYC1.ALTER.NET (146.188.179.82) 38 ms 51 ms 51 ms >> 5 104.ATM7-0.TR1.ATL1.ALTER.NET (146.188.136.57) 80 ms 87 ms 133 ms >> 6 100.ATM7-0.XR1.ATL1.ALTER.NET (146.188.232.85) 91 ms 141 ms 63 ms >> 7 195.ATM10-0-0.GW1.JAX1.ALTER.NET (146.188.232.169) 53 ms 81 ms 107 ms >> 8 bs-jackson-gw.customer.alter.net (157.130.65.226) 107 ms 132 ms 96 ms >> 9 172.17.80.46 (172.17.80.46) 59 ms 53 ms 44 ms >>10 172.21.210.18 (172.21.210.18) 122 ms 96 ms 49 ms >>11 209.149.111.17 (209.149.111.17) 53 ms (ttl=118!) 58 ms (ttl=118!) 150 ms (ttl=118!) > > > >Ok, now let's look up the 172.* addresses: > >>world% arin 172.17.80.46 >>IANA (IANA-BBLK-RESERVED) >> Internet Assigned Numbers Authority >> Information Sciences Institute >> University of Southern California >> 4676 Admiralty Way, Suite 1001 >> Marina del Rey, CA 90292-6695 >> >> Netname: IANA-BBLK-RESERVED >> Netblock: 172.16.0.0 - 172.31.0.0 >> >> Coordinator: >> Internet Assigned Numbers Authority (IANA-ARIN) [email protected] >> (310) 822-1511 >> >> Domain System inverse mapping provided by: >> >> BLACKHOLE.ISI.EDU 128.9.64.26 >> NS2.INTERNIC.NET 198.41.0.11 > >and I get the same result of course for the other 172 address so I'll >save you the redundant cut and paste. > >What's going on here? > >-- > -Barry Shein > >Software Tool & Die | [email protected] | http://www.world.com >Purveyors to the Trade | Voice: 617-739-0202 | Login: 617-739-WRLD >The World | Public Access Internet | Since 1989 *oo* > > ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Plain Aviation, Inc [email protected] LAN/WAN/UNIX/NT/TCPIP http://www.av8.com ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
