ANT Reverse DNS Crawler


The ANT RDNS crawler discovers reverse DNS names for the entire IPv4 space, quickly, politely, and correctly.


Our 2013 RDNS crawling software was developed by Lin Quan, John Heidemann, and Yuri Pradkin.

In Summer 2015 Romello Goodwin developed a completely new implementation, advised by Yuri Pradkin and John Heidemann, as part of a USC SURE summer undergraduate internship.
