How does IP address fingerprinting work in IP v6? I am not an expert but as I understand there are just too many addresses to establish patterns.
- nisa 2y agoIPv6 is more like /64 is an IP. Most ISP assign a /56 or /60 to the customer, you can just disregard all the other bits and basically have something like an IPv4 equivalent.
- topranks 2y agoTrue. It’s kind of the reverse of IPv4. In v4 you could have a million people behind one address. In v6 you at maximum have one person behind an address, but that one person may actually be using a million addresses.
- prasadjoglekar 2y agoExactly. IP is but one element of the fingerprint. Browser, OS, language etc. all make it quite possible to reassociate a user to a different IP v4 or 6; just takes a bit of time and processing.
- unethical_ban 2y agoIt's actually easier to track. Less NAT, ISP leases can get more specific,misconfigured privacy options... When I did a geoip lookup on my v4 address last year, it had me about 1.5 miles away from my apartment. When I did it on v6, it was within a block. Using a VPN and NAT will still be useful for privacy with ipv6.
