I am looking to setup a public DNS server and I found this DNS server

https://technitium.com/dns/

Does anyone know what the risks are of exposing the DNS port to the internet? How likely am I to get compromised? Is this a really bad idea?

    I ran my ssh behind 53 for a while because it’s rarely blocked. A few bots even got it right and figured out it was ssh.

      This is why the concept of running services until different ports than default isn’t a real security measure, it doesn’t actually take any effort to figure out what kind of service is running on a port.
