"Until a fix is provided by Apple, OIT recommends not connecting your iPad device to the campus network as it is likely it will malfunction."
"These devices are continuing to use an IP address they have been leased well beyond the time they should. (In technical terms, the device's DHCP client software stops renewing its lease, but the device keeps using the IP address after the DHCP lease expires. This is not a WiFi issue.)"
The only possible excuse (for the network stack developers) is that your parent operating system suspended, and that you weren't able to track how much time had passed - but, iPads (in my limited experience) are pretty good at tracking time.
Maybe they overlooked this because iPhone gets the time from mobile networks?
Anyway, I wouldn't be surprised to find out it's a long embedded bug.
