AT&T demands we change our networks
Interesting article discussing that AT&T appears to be getting ready to change their IP addresses on U-Verse (and maybe DSL) to 10.x.x.x numbers. In other words to save on real IP addresses they will NAT their entire network. So, anyone using their service will not be able to use 10.x.x.x private networks, and will have to switch to 192.168.x.x or 172.[16-31].x.x networks.

Fourth and lastly, there's the issue that, as far as I can tell, come July 6, everyone on the AT&T U-verse network who finds themselves front-ended by AT&T's NAT service, will also find services such as their Dynamic DNS (DDNS) will not work. Their DDNS updater will find that their Internet facing address is 10.x.x.x and, as far as I can figure it, that will not be resolvable back to the user's network because it will be part of a private address space.
