I debated posting this to this list instead of mailing it privately,
but I decided the response had some pedagogical value, for some folks,
anyway (and y'all who needed to know this are invited to write
privately and tell me so, so I have some ammo when randy and jhawk jump
my shit. :-)

The on the lookup implies that the port belongs, physically, to
UUnet; the tnt1 means it's a dialup port on the Tampa, Florida, POP,
which is an Ascend MAX TNT.

You'll have to send it to uunet, to find out which of their lessees'
customers it is, they should be able to look it up in radius logs,
based on the entire headers in the message.

Note that you may have to explicitly point out to them that you _know_
it may not be their customer, and that you also know that they _can_
look up whose customer is _is_ and forward the report along --
otherwise they've demonstrated a disturbing habit in the past of
playing dumb, at least with me.

something criminal appears to be involved, in which case, send it to
