I first met Garth Bruen over a year ago after hearing him speak at a security conference. His company KnujOn has pioneered some interesting methods for fighting illegal online activity.
Recently tasked with culling an investigative report involving several thousand ip addresses (after de-duping), I Reached-out to Garth to ask him if he was aware of any automated ip look-up tools. I had found a few ip look-up Web sites that spit back all the information I needed for my report
(http://ip-adress.com/ip_tracer and http://whatismyipaddress.com for example), however my report was quite detailed, and the look-up sites placed limits on their number of daily inquiries as well as the type of data one could extract from those queries.
Turns out, Garth and team had run into a similar issue a few years ago, so they decided to write their own tool to perform the aforementioned types of extractions. KnujOn charges a reasonable fee to perform batch ip look-ups and extractions, but I am confident you won't be disappointed with what you get for the price.
