Look up or Track IP Address

This program performs an IP address lookup and finds the ISP (Internet Service Provider) and country of origin. If possible, it may narrow it down to the city in which the ISP is located (not necessarily the same city or geographical location of the "owner" of the IP. The accuracy is not 100%, but close enough.


example: 129.128.22.33

What is Arul's IP Address Tracking Program used for?

I created this online IP address lookup in the year 2000 and it has been running since then. It was initially written to track an abusive email sent to a classmate. Yes, the culprit was revealed. Since then, I expanded its functionality and use into other areas. Some of the use cases are:

  1. You get abusive mails from somebody and want to know where it has come from!
  2. Someone claiming to be a prince or sheikh emails you, and you suspect that he or she is from another place.
  3. You just want to track an email you received from an "acquaintance" or something.
  4. You want to trace an IP address or do an IP address lookup out of curiosity.
