IP question

I need someone who knows how to search an IP, at least better than I can. Please PM me for details. I appreciate the help.

I tried your second suggestion before I posted my inquiry and found a little info. I would like to dig a little deeper, if at all possible.
Thank you for the suggestions, very kind of you!

"Search an IP" - what exactly are you looking for?
An IP is assigned to a subscriber - it could be static, or dynamic (in other words, the person who uses that IP may change)

Short of requesting a court order, it may not be possible to find out who was using that IP at a specific time frame (if it was dynamic).

Like Jake said the most you could out of an IP is who their provider is and maybe a city

You can use that to find the node where that IP was assigned. Other than that, you're SOL unless you get someone to subpoena the ISP.
