How useful is an internal Lan IP? I’d imagine for most people it’s just 192.168.something or 10.something. Though if you’re on IPv6 is it just the same was your public IP?
I choose a quite obscure LAN IP so it’s less trivial for someone who gets past the firewall to target a host. There are thousands of LAN subnets, so once you divide a non-unique fingerprint into thousands, it’s quite trivial to identify unique hosts, particularly if the traffic to a particular site is not in the thousands.
Even running a browser add-on/extension is sufficient to alter a fingerprint to be more unique.
