What happens if the ISP never defines a name server with their RIR for their provider-independent address space? Does ARIN point to somewhere which supplies NXDOMAIN? Just a thought -- I don't have a clue. It is entirely possible they have it pointed to their non-existent or broken DNS. Given current best practices, I see no reason not to assign a generic x.x.x.x-dynamic.customer.isp.com DNS across their netblock.
I think that returns SERVFAIL somewhere down the line? Does it make sense to reinforce the behaviour (good and bad terms left for another time), while looking forward to v6?
