iOS 5 iPhone Activation via WiFi

What ip address or ranges of ip addresses for the servers that the iPhone communicates with when going through the setup steps when first activating the device in ios 5?

A little background:

We as an enterprise have two types of wifi; guest and secure. Our secure wifi is wpa2 with certificate authentication and is strictly for only enterprise pc's. The guest wifi is generally for vendors and contractors, and only gives them access to the Internet. The guest wifi is open but has a web authentication page that the user is redirected to when trying to browse to any web page.

We would like to use the guest wifi to activate the iPhone instead of connecting it to a pc with iTunes. But since we can't get to the safari app while stepping through the setup procedures when first turning on an iPhone, we cannot get to the web auth page to get Internet access.

We do have the ability to write an acl in the wifi to allow certain traffic based on source address, destination address, protocol, port, dscp, tos, etc. We have tested that this acl will enable us to allow certain destination addresses without having to web auth. If we knew the ip addresses of the servers that the iPhone talks to during activation, we could permit those without requiring web auth, while still maintaining the web auth requirement for anything else.

We have tested this with a new iPhone being activated using the wifi and logging the traffic as it attempts to reach the Internet. From this we have observed it communicating with servers in the following ip ranges:

17.0.0.0 - 17.255.255.255

199.7.48.0 - 199.7.63.255

We also observed several Akamai servers that were communicated to, but not sure if there are any consistency with those servers, or if we will need to try to incorporate all known Akamai ip addresses.
