If an end user has routinely submitted their physical address in Web forms, it’s probably in one of these databases. For customers of Comcast and many residential broadband providers, DHCP hands out a hardcoded per-customer or per-CPE IP, not the next available address from a pool. For all intents and purposes, the DHCP-assigned address is static. At least as of a year ago, Comcast support won’t let customers change their effectively-static “dynamic” IP.
