Princeton University Network Has Issues With iPad
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.

Damn, do Ipods have the same problem with DHCP? It seems Apple's Tigger team A does not know what Team B is doing. Typical major corporation snafu. It should be resolved easily. But this leaves the door open to hackers who can flood the campus with IP address requests and never release these. Slick way to wreck a fellow student's use of IT resources.

Well if they were smart they'd have a lease time of 24 hours or less, I've been in some hotels with 4 hour lease times for DHCP, and I've been in some with a full week. Their network administration could easily work around this problem if they wanted to, they just wanted to get in the news and mentioning the iPad is an easy way to do it.

You are assuming that the DHCP implementation on the iPAD is a well behaved one.

Oh no, without looking at the iPad's implementation (and I haven't bothered) I'm not saying it is well behaved. Bad Apple if they didn't QA their DHCP client properly. But, this can't be the first bad client their network has seen before.

Yep. I agree. If you're not properly implementing the DHCP protocol your device should be blocked, easily enough. They can find the offending MAC addresses and refuse to give them addresses.
I don't know what the problem Princeton is claiming. But if it were something that simple, wouldn't everyone be noticing it? So far my iPad has been through 4 hotels and 6 airports in addition to my house, bouncing from DHCP server to DHCP server, no problems yet that I can see. |

Yep, this is definitely an irritating problem. I'm sure they will put out a fix soon. As far as I know the iPhone does not have this problem.
