IP Country Lookup is a free DNS utility for Windows that lets you lookup the country an IP address or hostname originates from.

It uses a locally installed file containing a list of networks and associated countries to quickly determine the geographic source of an address.

IP Country lookup is provided entirely free and is not a trial or crippled version of the application.

Determing the source country of an IP has many possible uses including analyzing network logs for malicious activity, detecting online fraud, tuning spam filter configurations or simply finding out where in the world a server is located.
