And the one big reason that no one has mentioned (that I have seen) is
that the IETF just recently released a BCP (best current practice) that
states that ISP's should not use static IP addresses for dialup users
because all this does is contributes to backbone router collapse (do to
ridiculous sized routing tables) and makes it next to impossible for an
ISP to make simple network changes.

I will refer anyone who takes an interest in how the Internet really
works and how changes will affect you in the future to puruse the USENET
newsgroup info.ietf.
