You give a USA specific example, so I'll give one from where I live: aside from a few (like Google, Facebook, LinkedIn) that I suspect do things like recommendations or friend suggestions based on our static IP address, in the Netherlands it's virtually nonexistent. And illegal, at least without telling us that they do tracking (no matter if it's through cookies, the law never even mentions cookie). Header injection (MITMing traffic) is something I only hear about from far away and seems very invasive to me.
Same in Germany, but there they have rotating IP addresses (which is both a pain (hosting) and a blessing (privacy)).
Hmm, although, would MAC address tracking count? That happens here and there (by roughly the same amount in any EU country, as far I can tell, which is not very much), mostly with WiFi captive portals where you sign away your soul in the terms of service. I'm not sure about the legality (hiding GDPR consent in the TOS) but it happens. From experience, I can say that if you find out and you send them a letter with a copy of your ID, they'll happily give you all the data they have on any MAC address you claim.
- Left4Yee 7y agoI caught Vodafone and Telekom in Germany injecting headers. The former for shady cooperations and tracking, the latter for cache screwery. The latter did dns modification to turn nxdomain into a navigation help, a site that looks like google but everything is ads. Vodafone CPE equipment saves all mac adresses ever present in the local network and unassociated wifi client macs in the air and sends them back as part of diagnostic data. Edit: They also DNS Censor popular warez sites and libgen

- rocqua 7y agoRegarding MAC tracking, I found a sticker in Centraal Station Utrecht that said 'wifi tracking' with 'voor meer informatie: www.ns.nl/privacy' Edit: the relevant privacy page is: https://www.ns.nl/privacy/op-en-rondom-het-station.html https://www.ns.nl/privacy/op-en-rondom-het-station.html which also has an image of the sticker I saw.
- newscracker 7y agoApple’s operating systems have been randomizing MAC addresses since late 2014 (or before). So the MAC address has not been a unique device identifier for users of Apple devices.
- lucb1e 7y agoDon't they use the same MAC for the same network? So when it reconnects to the same network, doesn't it adopt the same MAC as before? Otherwise one could not give a device a static IP in DHCP. I'm not sure but I think I remember reading this. And it would mean that hotspot tracking (the most prevalent form as far as I've noticed) still works.
