I have my DSL router-modem reboot every night, and I get all sorts of crazy results for ads: I'm in southern Ontario, as is my ISP, but they service folks in Quebec, and so sometimes I get Youtube ads in French since (per my IP) I'm "in" Quebec. Similarly with the reboot I get a new /64 prefix delegation (actually /56), so I would hazard to guess if IPv6 starts getting tracked, I'd get the same crazy results.
