Targeted advertising affects the entire pool of addresses behind NAT?

Question

Marketing

Many people access the Internet from one router, one of them has targeted advertising, the other has the same one, it turns out that the target acts on one IP and is already distributed to the entire pool behind NAT?

Answer 1

Well, if the owner of the advertising platform has implemented ad targeting only by IP, then it is. if he implemented advertising targeting by a set of parameters, then no.

Answer 2

The ad target doesn't know if you're behind the nat or not
