after six reports that 192.5.5.241's address has been forged as the source
of a tcp "fragmented scan" probe, i'm ready to have it stop. but just in
case it doesn't, this is fair warning to the community: F's address is in
unlawful use by as-yet-unidentified third parties.

To whom it may concern,
The Security Information & Analysis Center has detected an
unauthorized scan against one of our networks that has a possible origin at
192.5.5.241.
Please review the following initial information:
IPHalfScan 08-11-2002 17:34:02 UTC 192.5.5.241:53
xxx.xxx.xxx.xxx:53 TCP
IPHalfScan 08-11-2002 17:28:00 UTC 192.5.5.241:53

Please take action to verify this address on your network
and it's intent to scan our networks. Thank you for your assistance.

Modern DNS software finds the TLD Clusters, tracks them, and
does not use ANY "root servers" (legacy or alt). People who rely
on a dozen 32-bit IPv4 addresses to be coherently routed are fools,
in my opinion. Any organization that promotes that type of structure
and architecture as "secure" is perpetrating a fraud on unsuspecting
users, who assume the system is stable and secure. Root servers are
out of date, do not always track the TLD Cluster(s), do not support
fail-over to back-up TLD Clusters, in cases of a major corporate
failure. People continue to use them at their peril, yet clearly profit
from telling people to use them.
