Geolocating an IP address


Identifying the location of an IP address helps system administrators in many situations, such as when tracing the origin of an attack, a network connection, or a harmless poster in their forums.

Gorjan Petrovski submitted three Nmap NSE scripts that help us geolocate a remote IP address: ip-geolocation-maxmind, ip-geolocation-ipinfodb, and ip-geolocation-geobytes.

This recipe will show you how to set up and use the geolocation scripts included with Nmap NSE.

Getting ready

For the script ip-geolocation-maxmind an external database is needed. Download Maxmind's city database from http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz and extract it to your local Nmap data folder ($NMAP_DATA/nselib/data/).

For ip-geolocation-ipinfodb an API key is needed, so you need to register at http://ipinfodb.com/register.php to get it. This service does not impose a query limit, unlike Geobytes, so I highly recommend grabbing your own API key to enable this script...
