Logging all user IP addresses

[_saiko]

I realize that the registration IP and post IP addresses are logged, but are all the IP address that a user used while only browsing the forum logged?
I.e user has a dynamic IP, posts rarely - is there a way to log all the IPs he used while only browsing and not posting?

Thanks

No, only the IPs in posts and the last two different IPs a user uses are actually loged.
