Whois providers

FireStats support multiple services that resolves the IP address, such as ARIN and RIPE.
Its possible to add additional services by editing the file php/whois.txt.
The syntax of each line in the file is as follows:
NAME URL

• Name: the service name.
• URL: The query URL, where the actual IP address in the URL is replaced by %s

for example, this is the line for ARIN:

ARIN http://ws.arin.net/cgi-bin/whois.pl?queryinput=%s

If you would like me to add a new provider to FireStats please open an enhancement request.
