Hi, there,


I'm an network administrator who is working in an enterprise.


There are almost 1/3 people are using iDevice like iphone or ipad. Recently, I found when some colleagues connect their iDevices to the computer via USB port, their iDevices were getting extra ip addresses in our DHCP address pool, which means those iDevices also got IP addresses from our DHCP server by connecting the computers in the company.


I've checked that all those devices have upgraded to iOS5, and no matter they did sync with itunes or charged only, the issue still existed.


My problem is how to stop those iDevices to pick up the ip addresses from the DHCP server. Thank you.

iPhone 4, iOS 5.0.1
