I'm considering moving to AT&T DSL from my current cable provider, Mediacom. I was reading about the DSL service on AT&T's site and they mentioned that customers get a dynamic IP address so that every time they "log in" to the Internet, they have a different IP. I have no problem with dynamic IP's, but what do they mean by "log in" to the Internet? I thought DSL was the same as cable in that you're always connected. Also, they mentioned several software items that come with their service, such as pop-up blockers, SpamGuard, customizable browser, etc. This almost sounds like something AOL would do, installing all kinds of junk software that you don't need or want. Can I opt to not install ANY of this stuff and just use Firefox like I always have with my cable provider?
