Maxmind and Google Maps Mashup [php]
March 8th, 2008
I was bored today so I created a very simple and fast php script to plot the location for a given IP and display other IP information (such as lattitude, longitude, Country, State, Area code, ISP, etc.) on a Google Map using the Maxmind web service and the Google Maps API.
The link in the balloon points domaintools.com and does a whois lookup on the IP for detailed information on the ISP (internet service provider).
Here is a working demo (hard coded IP).
In order for this script to work on your site, you will need a MaxMind GeoIP City/ISP/Organization Web Service Key (50,000 lookups for $20.00) and a Google Maps Key (free). There are other IP to Lat/Long Web services out there but Maxmind is by far the most accurate (none are 100% accurate).
To render the location of an IP on the map, send the IP via the query string such as…
http://www.yourDomain.com/MaxmindGoogleMap/index.php?ip=98.195.83.50
Here is the script. Copy the contents to a .php file and edit the 2 keys. That’s it!
