Determining company name from IP address

Question

I apologize for the broad question. But I have a list of IP addresses, and would like to connect them to the companies they came from.

I\'m not interested in identifyin

If you have the IP address you can go to who.is and enter the IP. If you then scroll down you will find a feild where it says "OrgName:" and there you got it :)
