Just had a case today where a downstream "clueless" tier-4 ISP got a new
customer. The "clueless" customer wants his /24 to be announced. We asked
for proof of ownership. Clueless customer sends official letter to
clueless tier-4 ISP, who tells us "route it now!" We do a check in APNIC
and see it is part of a larger /19 assigned to someone else (probably
clueless's customer former upstream ISP). We told clueless tier-4 ISP that
we can't announce the /24. I am now waiting for an email stating "but
Bulbul ISP never checked APNIC, so why should you?"
These battles are won slowly and one at a time.
