The fpdns tool was first introduced more than 20 years ago. It gained popularity in both research and operational communities, and was actively used to fingerprint DNS software at scale. Unfortunately, it has not been updated for a while. We are currently working on its successor - fpdns2. We set up more than 670 instances of recursive resolver software from 7 vendors and issue a series of DNS queries that effectively distinguish vendors and versions. With this presentation, we wish to present the first prototype of our tool and hope to obtain some valuable feedback from the community.
