I put up a site and saving all the IP addresses of users is adding some overhead. I am trying to figure of this benefit is justified.
I never used an IP address for anything other than correlating user activity for trending and site usage metrics.
I know the IP information can be used to audit and trace things back to the user of that IP.
what exactly is the info you can gather that would be useful based sole on the IP address and how can i get this info?
