security - what info can you find out by knowing an IP, how and what tools/ sites are needed for this? -

-

i put site , saving ip addresses of users adding overhead. trying figure of benefit justified.

i never used ip address other correlating user activity trending , site usage metrics.

i know ip information can used audit , trace things user of ip.

what info can gather useful based sole on ip address , how can info?

if user criminal can report them fbi. trying block attacker based on ip address short sighted. proxy servers free, ip addresses pennies.
