The Princeton University IT department has issued a warning to all students who use iPads on the school's network.
The warning asked the students to refrain from using iPads on the network. It also stated that if a particular iPad was identified as the cause of a disruption that it would be banned from the campus network completely.
According to the Princeton IT department, when iPads are used on their network they are not releasing their server assigned Dynamic Host Configuration Protocol IP addresses when the lease expires.
