Re: Tell me about AS19111

In article <8930.1580963430 () segfault tristatelogic com> you write:
1800vitamins.org has a web site at 12.180.219.234 which looks like
they would sell me vitamins should I or my dog need any.

Routeviews tells me that IP is in AS19111, routed via AS7018.  AS7018
is AT&T which isn't surprising for a 12/8 address, but ARIN says
AS19111 doesn't exist.  Huh?

John you have no idea how many folks are using how many bogon ASNs
as we speak.  Nobody does. ...

The reason I originally asked about this one is that everything looks
entirely legit other than the ASN.  It appears that the only reason it
is bogus is that the vitamin company isn't very good at remembering to
pay its ARIN bill.

I get the impression that's fairly common, since the practical penalty
for having your ASN fall out of the database is zilch.

R's,
John
