I've seen several articles on this phenomenon, but none of them seem to address the real issue. I understand that banning the iPad from a network may be necessary in the short term. But over the longer term, if single device can wreck your network just by using an address for a bit too long, then there is something wrong with your network. I'm still waiting for the headline that says, "Security hole found in DHCP[1]; iPad accidentally exploits it". Hasn't happened yet. Why not? [1] Or wherever the root problem turns out to be.

It doesn't "wreck your network", rather, when it keeps its DHCP lease beyond the allowed time (due to being in "screen off" mode during the expiration) it wrecks things for itself and whomever is unlucky enough to have gotten reassigned the same IP address. Not a security hole, just a "doesn't play well with others", and I can't think of a way to avoid this without going outside of DHCP (e.g. assuming bad behavior and therefore using a big enough pool and not reassigning IP addresses for a long time).
