why is the local ip considered private information?
99% of people are going to be in 192.168.1.0/24 or 10.1.1.0/24. so it only takes 508 guesses.... not to mention that everyone is 127.0.0.1.

- cpeterso 10y agoA site can very reliably identify you (across browsers, even) if it knows your public and private IP addresses. Your public IP address identifies which organization or network you're in and your private IP address identifies which machine within that organization or network you are using.
