IPV6 also greatly complicates IP-based blocking. There are so many IPV6 addresses that it'd be relatively cheap for an ad tracker to develop a system that uses a new one every day.
- half-kh-hacker 6y agoIf you get allocated a /32, you have 95 bits of addresses to play with. You could use a different IP every millisecond and not have problems.
- near 6y agoWhat would be wrong with blocking the entire /32 if you know the owner of it is using it in such a way?
- citrin_ru 6y agoAd trackers often use some ISP or cloud provider with many other customers. Which network ISP assigned to a given customer is not public information. Even if a company has own AS, blocking it not always an option: Google, Oracle, IBM and others potentially can use any IP in their networks for Ads, but too big to block.
- deadlyllama 6y agoYeah, but they'd all be in the same /32, which is trivial to block. You'd have to intersperse "legitimate" users through your space to thwart that.
