Author: Sherman Richardson   
Submitted On: 16 October 2012

Description: I am a college student majoring in Information Systems Security, and one of our projects is to use the resources of your whoi-is service to determine the IP addresses of 3 universities’ and find out if your service can determine the geography of the specific IP addresses (with accuracy). My question is how do I do this?

Thank you for contacting us regarding Whois. As you may know, ARIN’s Whois service gives contact and registration information for IP addresses, autonomous system numbers (ASN), organizations or customers that are associated with these resources, and related Points of Contact (POC). It doesn’t include information on domain names or military networks.

We provide a web interface to Whois data at - using the search box in the upper-right part of the screen, you can search for specific IP addresses and organizations and get back information regarding the networks and organizations associated with those Internet number resources. Actual geographic locations of where these IP addresses are used are not part of the dataset in Whois and ARIN does not track or provide such data.

Documentation on how to use the Whois service is provided at:
