If you are using the new AT&T UVerse service, recycling your gateway will take out your TV, VOIP phone, etc. for several minutes. In addition, the pool of IPs is such that if you do reconnect, you are likely to get the same IP.
You should be able to recycle your IP on your regular AT&T DSL just by recycling your modem (gateway, etc).
I just got AT&T UVerse, and while it is very cool, I've screwed the pooch WRT my CL marketing. I've started using ProxyFirewall (thanks ApeKillApe for pointing me to it), but so far the proxies that I have had are not working well. PM me if you know if a good proxy server provider that is compatible with Craigslist.
