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.

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.
