Thank you for everyones insight. I learned a few things, mainly, RADB
is not a valid source of authenticating rights to IP blocks, RIRs and
Arin still trump RADB for legacy blocks. I also didn't think to check
all the other RIR's whois databases. Just did that, and it didn't turn
If the customer can't update the Arin info to make it look legit, then
its a no-go and I wont accept their BGP prefixes and their business.
At that point, I'll probably also send a friendly email to Arin with
the /16 in question and they can take a closer look at it to see if
any action should be taken.
On a side note, the /16 in question is currently in the global BGP
table, but... the two AS's it originates from are also "fishy" and
suspect - i.e. outdated POC's, etc.,..
