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. > This is a new(er) customer, so there is some merit to dropping the > prefix and letting them sort it out based on the current RIR > contact(s). However, there is obvious concern over customer service > and dropping such a large block of IPs. Size of the block often is a poor indicator for legitimacy. Kind regards, Job
