What do you mean? Just because Comcast leases you the same IP for years doesn't mean they're obligated to give you the same IP on your router's next DHCP request.

Quasi-static IP assignment, my favorite.
Sure, they aren't obligated but they must not be short on IP addresses if they are doing that. I added quotes around "static" to make it more clear.
Agreed. My Comcast public IP didn't change for a few years until I moved.
Did you change router as you moved?
Nope. Same router, same cable modem.
