It's more common than you might think, especially for small regional ISPs who don't have a large allocation of addresses from ARIN. For DSL subscribers, my ISP offers a choice of a static IP (private 10.x space) which routes through a NAT firewall, or a static publicly routable IP for a small additional charge. All dialup users get 10.x addresses and NAT by default.
