Movement refers to the "horizontal break and vertical drop" of a pitch against the average.[0] If a pitch has more break and more drop then it has more movement. A pitcher can increase these by increasing the spin rate[1]. That's why spin rate is all the rage these days among sabermetric geeks.

An example of using IPs to combat abuse is Wordfence. It's a WordPress plugin which blocks traffic from known abusive IPs. A quick glimpse at the "live traffic" for one of my websites reveals several IPs within the last hour that have attempted to access the site which were blocked.

A site I was repairing after a hack fortunately had server logs which included IP data. That IP allowed me to identify the specific exploit used.

So, there are definitely uses for IP data in security terms.
