How to collect passive dns data in an organization?

Question

Domain Name System

Good afternoon.
There was a task - collecting passive dns data for further analysis.
Do you have any ideas and suggestions how to organize this in an organization/company?

Answer 1

you for yourself? put a sniffer on your DNS server - and write all requests. as an alternative - you can put a proxy script for DNS, I once did this on python. He just acted as a DNS for the client, logged requests, and gave the correct ip or not the correct one, depending on some conditions.
