Dear Sean,

This is more or less the situation we're in. We contacted the customer
and they informed us the matter is in dispute with the RIR and that
their customer (the assignee) is in the process of resolving the
issue. We have to allow them time to accomplish this. I've asked for
additional information to help us understand the nature of the
dispute. In that time we received another request to stop announcing
the prefix(s) in addition to a new set of prefixes, and a threat to
contact our upstream providers as well as ARIN - which is not the RIR
the disputed resources are allocated to.

I've seen disputes too between end users and RIRs - usually this is due
to non-payment. It can be helpful to do two things: set a reasonable
deadline for the customer to resolve this, and verify with the RIR
whether the dispute is actually ongoing or whether the RIR closed the
case. Example case: customer said they were in dispute, but RIR
indicated that the case was closed. If the RIR closed the case, I'd lean
to dropping the announcement.


What are people's experiences with the various RIRs discussion of these
situations?
I believe sometimes (though could be mistaken) they consider these matters
confidential.

Perhaps there are official RIR policies stated on how they handle such.
It can be frustrating I'm sure.
For the situation you describe, I'd be inclined to say that if the RIR's
posted registration matches what you've got and has been so for a while,
that ought to stand.

Tony
