Each ISP has their own issues... Here Comcast will not allow a residential account to get a static IP. You have to subscribe to a Business Class plan and use their router/modem combo to get static IP(s). Putting their router in quasi-bridge mode so that you can use your own router (which is something many businesses would want to do) is problematic; some models of their gateway/router devices are known to be unstable or just not work properly at all in quasi-bridge mode. That, coupled with the fact that their tech support folks are not known for quick or efficient service, makes them barely tolerable as an ISP. Unfortunately, their main competitor in this area has their head firmly stuck in the sand as far as IPv6 goes. Last I checked, they had not even gotten as far as applying for IPv6 address space.
