We really have no objections to creating records for our IPs however there was no compelling reason previously. With the manifestation of performance issues, we are currently creating a generic record for our addresses. I assumed that the applications would take absent records into consideration instead of waiting and timing out before responding with data. Trying to troubleshoot this issue from the limited visibility is difficult ; the latency the application is introducing is abstracted (unless I am unaware of that troubleshooting technique).

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?
