Dennis : What IP address ranges.....

[jim]

I know this isn't your area of expertise, but if you could point me to the
right people at AT&T I would be extremely greatful.

What IP address ranges does AT&T/Bellsouth use?

I need this info for detecting whether a laptop is using the AT&T DSL
network or the user's Sprint wireless network.

Any Help you could give would be greatly appreciated.

Thanks!

What does this have to do with programming software using Microsoft's .NET
platform?
