ip2c (ip to country) is a program written to determine the country associated to a specific IP address. The program queries the five main whois servers responsible for each region of the world and try to automatically establish the most authoritative for the IP specified. Then it return the country's two-letter TLD (for example US), the extended country name (for example United States of America), its world region (for example North America) and a string containing a brief description of the organization managing the block of IP addresses containing the submitted IP (when available). The program can also process a list of IPs stored in a comma delimited file and generate a new file with the country fields added to it.
