AT&T Network IP range?

[dyerucf]

Any one know the ranges that iPhone traffic is likely to originate? I would like to limit my machines exposure and only pinhole this range if possible for a server process I run which the iphone connects. I am sure they have an entire class A network, but if any one has any idea of the logical ranges for iPhone cellular edge/3g traffic in the lower 48 please pass them along.

Thanks!

AT&T seems to run in the 10.13.178.xxx range for me in the Central/Southern Brevard area. Not sure this will help you in Orlando however.

10.x.x.x is private, non-routable (RFC1918) address space. Thats the actual IP your phone gets, but it translates into a routable IP. AT&T owns 32.0.0.0/8, so if you'd like to limit traffic to AT&T networks, 32.* would be a good start. If your in the same area, i'd go with a /16 pinhole (32.16.x.x).

doh! that is correct, will learn me for posting 3/4 asleep.
Current 3g/Edge IP 32.160.148.xxx
Current Edge IP 32.161.255.xxx
Curent 3g IP 166.195.119.xxx (odd)
dbl checked 166.192.17.xxx (odd)
I've got a 166.19X.x.x a few times now missin' around with switching 3g on/off Edge on/off only.
After a hard boot it settled back into the 32.16x.x.x range

Speed Test app is reporting:

Internal IP: 10.3.214.xxx
External IP: 166.190.172.xxx

Would it be correct to think about it like this: the 166. IP is the "real" public IP seen by the whole internet, and the 10. IP is kind of like AT&T's own router, through which they disburse IPs to their customers, kind of like a home router and a 192. IP, but on a much larger scale?
