My laptop was stolen.

It is usually locked but was unlocked,so they have managed to get into it. 

It was an old Windows 7 Acer computer with Dropbox Desktop installed, so I have their IP address (122.x.x.x) from Dropbox and can see when they turn the computer on. I can see the ISP is Spark.

Are there any tools which might be able to get more information on the IP address?

(such as a street address)

I can upload files to the computer via Dropbox as well!
