Maybe I'm misreading this but...

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

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?
