And then every website starts doing the CNAME nonsense.
- falcolas 6y agoIf it’s only a CNAME, you’re one DNS lookup away from continuing to block it. One DNS lookup you’re doing anyways.
- tick_tock_tick 6y agoIt's random CNAMEs and they use the unique cname you queried as another tracking point.
- WalterGR 6y agoI didn’t know what you meant, so for others equally confused, this is a decent article: https://www.theregister.com/2021/02/24/dns_cname_tracking/ https://www.theregister.com/2021/02/24/dns_cname_tracking/
- bpodgursky 6y agoI don't understand the hate for this trick. It still breaks cross-site user tracking. It's just sort of a hack around installing a hypothetical Google Analytics app on-prem or pumping in data via a server-to-server integration. Google Analytics can't cross-reference data from other sites on the browser, b/c it's not a third party cookie now... what's the problem?
