AFAIK FB will do semi-targetted advertising based on IP alone if there's a very small number of users logged in from that IP.

On mobile your IP will change every few hours.

Anyway the very idea that people are making money from me keeps me up at night so I use FF with a bunch of privacy aiding extensions. The war to fingerprint users is endless though. Ad tech is a billion dollar industry.

That happened behind my ISP's NAT in a densely populated area, so I don't think so, no.

I'd be surprised if it was the only thing they used, to be fair. But there is fairly obviously some IP-specificity going on.

So you need to control your IP address but your example shows it doesn't matter?
