We just added a new site preference to log IP addresses anonymously, which takes the last octet and changes it to 0. For example, 123.123.123.123 would become 123.123.123.0. And we’re not just hiding the last octet from you – we remove it before storing it, so it should comply with laws in places like Germany where it’s technically illegal to log the full IP address of a visitor.
This preference is available to all users. You can find it in your site preferences, under “advanced”.
