IPNetInfo is a handy monitoring utility that will easily find all available information about an IP address: The owner, the country/state name, contact information, and more.

This utility can be handy for finding the origin of unsolicited mail. You can copy the message headers from your email software and paste them into IPNetInfo utility.

IPNetInfo automatically extracts all IP addresses from the message headers and displays the information about these IP addresses.

The IP address information is retrieved by sending a request to the whois server of ARIN. If ARIN doesn't maintain the information about the requested IP address, a second request is sent to the whois server of RIPE, APNIC or LACNIC.

After the IP address information is retrieved, IPNetInfo analyzes the Whois record and displays it in a table. Quickly find out various IP information using this simple utility.

Notice: From time to time, the WHOIS server of ARIN is down and doesn't respond to WHOIS requests from IPNetInfo, and thus IPNetinfo fails to retrieve the IP address. When such a thing occurs, try again later.
