AS2 is the most hijacked prefix in the world. Yes UD still owns it,
but since different router vendors use different methods of prepending
AS numbers, many folks try to prepend twice and end up announcing
on AS2..

I think the most common way to get out of this DB is to not pay
something.
I'd guess that
aut-num: AS37451
as-name: CongoTelecom
descr: CONGO TELECOM
has a relationship with them and AS327933 wanted to prepend 2x [1] to
their sole provider..... (AS37451)
We are seeing some weird routing from them, and the AS2 they are
attached to (University of Delaware) seems odd.
Not sure if any of the American folk on this list can verify AS2 is
really part of the University of Delaware...
