a little over half the bytes of a typical IPv6 visitor's address is comparable in identification to what all four bytes of an IPv4 address tells you
- ninkendo 6mo agoI'm not necessarily talking about fingerprinting or tracking here, it can be something a lot more mundane. Like if I have a homelab setup and I want to see what hosts connected to something, and I look at the logs and see privacy addresses, I know I'll never know what host it was. Or if I want to set up netgroups for access control to shares or something (just a hypothetical.) In the classic sysadmin world, the idea that an IP you see could belong to any host and you have practically zero way of knowing, is rather different from what we expect in the IPv4 world. You just have to embrace it, basically.
