How much tracking can you do on a v4 DNS? There can be thousands of people behind the same IPv4 at a given time, or it could change in a matter of minutes. A state could probably be able to exploit that (as in there is a political opponent living at this address) but if the aim is just to track an individual’s browsing habit I would think it is impractical.

IPv6, other debate.

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.

I have an IPv6 address that has never changed. My IPv4 address changes fairly often. The DHCP servers most definitely log the end-point MAC which can be tied directly by the ISP to my modem and router behind it. It's fairly easy to trace this stuff, if somewhat impractical.

Well, they do seem to plan to offer IPv6 DNS. And you'll probably want to be using that anyway, although they don't seem to recommend using that, as they mention it only briefly.
