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

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) iana@iana.org (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?

Or Bellsouth is using Alter.Net for their transit provider just as US West is in the Pacific NW... Tim ---------------------------------------------------- Timothy M.
