They only change your IP address if you don't renew your DHCP lease often enough. Unless there was a recent change in their network, your router address is always ${ip%.*}.1, so I'm not sure why yours would change while your IP addresses remain constant. The formula to generate the gateway address even used to be in some of their documentation. Reverse lookup should work, by the way. It was broken for a short time after @Home pulled the plug on AT&T subscribers, but mail generally works fine now. The exception is people who blackhole AT&T's netblocks. I have only noticed two people who do this, one of whom is Eric Anderson. ;-) If you care enough, you can always work around that provided that you have a login on a machine with a more respectable Internet connection. However, I don't recommend using AT&T's mail services; I have recently noticed that their servers don't always get the mail delivered.
