Almost none of the broadband providers in the US NAT their
customers.
Well, I suppose I have been unlucky then because every single one I have had has NATed me. I had a "real" IP when I had dialup, but I got NAT when I went broadband. I have a friend that has another service and she is NATed too. Boot up in her network and you get 192.168.1.x
In other words, the broadband provider provides a single global IP to the "always up" CPE. That CPE does DHCP to user stations and hands out 1918 addresses and NATs them to the single global IP. I have had 3 broadband providers over the past 10 years, all three have done that. I have a friend on a fourth provider that also does that. I have yet to see a broadband provider that configures a network so that individual nodes in the home network get global IPs.
