The ip feature was good to see if people were using proxies or you could test people by asking what country they are from then check their IP to see if they were telling the truth, if they weren't then that could possibly mean they are fraudulent etc. @Admin why was this feature removed?
Yes, it's an awesome feature but only available to Verified and Above Members for security reasons. If you can't view it, then it's likely to do with some user group settings. I will look into this and update you within a hour.
