However we are quickly running out of IPv4 addresses, so I'm guessing soon enough they won't be offering the static option at all.
You don't get a new IP every time you reboot your modem or computer.

DHCP servers have a "lease" time that basically states you have the IP for a certain amount of time and depending on the ISP it can be a short time or a long time.

And the whole IPv4 vs IPv6 .. we won't see IPv6 in a home for a long time. There is still a lot of IPv4 ips to go around that never get used.
