Hi Aftab,

You can reasonably think of a bogon as any Internet number resource
which according to the registration authority should not appear on
whatever network is at issue.

The RFCs offer guidelines and conventions in this, not hard rules. It
would be an error to treat them as hard rules.

In my opinion: until the customer stops paying you or the authority
assigns the resource to someone else. As long as the resource was
properly assigned to the customer when they started advertising it,
there's no real angle to forcibly ending it sooner.
