whatisonip.com API

whatisonip.com is a reverse IP address lookup service with a large database of over 159M domains updated weekly. The API functionality offers 3 methods of extracting data from the site: information related to the sites hosted on a single IP address, information related to the sites hosted on a C Class of IP addresses, and information about the sites that share the same reverse DNS. This allows users to find blacklisted IP addresses, IP address location, and information about what sites run on a certain IP address or IP address class. The API envelopes basic HTTP calls and XML responses.
