Your IP address tells websites and ad companies a lot more about you than you might realize.

My latest for the Startpage blog.


IMHO, the described IP leaks are not very useful for ad companies, because nowadays most people have dynamic IP addresses and, more over, NAT.
"Raw" IPs expose a messy mixture of traffic from up to several hundreds devices which seems useless. (Unless ad companies coop with ISP and know the sequence of IP reassignments.)

Am I right?
