Scanning for DNS resolvers

2013-01-31

For a research project I’m working on, it has become necessary to scan potentially large IPv4 prefixes in order to find any DNS revolvers that I can and classify them as either open (accepting queries from anyone) or closed.

Disclaimer: This is a form of port scanning and thus has associated ethical and legal considerations. Use it at your own risk.

This project is available on GitHub: jpverkamp/dnsscan

ISC/CAIDA Workshop

2012-10-22

I’ve spent the day in Baltimore at the ISC/CAIDA Data Collaboration Workshop learning about and presenting about all things DNS related. It’s not really the sort of thing that my PhD work is focusing on but it’s still interesting.
