No, they don't, sure in a given period of time they know how many unique IPv6 addresses are in use. But they can't tell how many devices that is. I'd much rather have 2^68 IPs that I can sprinkle over as many devices as I want than a single IPv4 that makes p2p hard, makes services hard, and requires the use of either NAT or tons of port forwarding.
