i beg to differ just because on a dsl line you can disconnect from the server doesnt mean you get a new IP address, you have a HARD line to the server, the sockets on the server would have to be changed inorder to give you a new IP address.
you might be confusing your wireless route giving you a differnt IP to use everytime you log on, that is int"ra"net not int"er"net
it is possible but i know of NONE that do.
AT&T doesnt, roadrunner, earthlink, aol none of them do they are using non proprietary software.
not calling you a liar but can you tell what DSL company uses dynamic IP's, i knwo of none and i work with several of the big incumbent carriers that supply the back bone of the internet (when it all comes down to it thou they all pass thru goverment owned and controled mainframes)
