Mrs P's link is as good as anything you'll get, but (unless you've got a court order) you can't identify individuals or locations from their IP address.
For example, my current address is 217.158.116.192. If you try to check my location, you'll be told that it's 'London' (because that's where my ISP is based), even though I'm in Suffolk.
My ISP allocates 'dynamic' addresses. That means that I'll be given a different address every time I log on. Further, it means that someone else will be given 217.158.116.192 as their IP address, after I disconnect from the internet. They might be in Cornwall or in Scotland, but a search will still show their location as 'London'.
If any of the users of that address were identified by "the authorities" as being involved in terrorism or distributing child pornography (for example) , they could get serve a court order on the ISP, requiring them to reveal who was using that address at the relevant time. However, 'Joe Bloggs' (i.e. you) has no way of accessing such information.
