I’ve stumbled into a strange situation where, querying my droplets on their public IP, I am getting a response even when no DNS server is running and the firewall is configured to drop packets on port 53.
Further, when I am running DNS on a droplet, everything works as expected when querying against the VPN or local interface of the droplet but querying it’s public IP, the response is not as expected and appears to be coming from another server on my servers behalf.
What gives? How do I stop this?
