Most residential ISPs use dynamic addressing vs static addressing. It may be the same for a very, very long time, but that doesn't mean that it's static. If it's always connected and powered up, then before the DHCP assignment expires, the device will send a DHCP request with it's current IP. The DHCP server will usually let the device keep the same IP. If the device is powered off for an extended period, then it will often come back with a different address. I'm not talking about the PC, I'm talking about the device that actually has the IP address assigned which is usually a router.
