My home IPv4 address from a major cable internet company hasn't changed in over a year and I don't have a static IP.

Even when they do change, knowing ping times plus IP address owner plus superficial usage patterns would easily be enough to narrow down to a single household. Many households will have a unique DNS footprint based on the exact makeup of internet connected devices in the household that are constantly phoning home.

People do often forget this about DHCP addresses: Most DHCP servers will renew your same IP for as long as practical, and this often spans years. At work, my NIC held its same lease for about two years, I was a little sad recently when I discovered it had finally changed.

How I monitor my house also lets me know when my public address changes, and its extremely rare.
