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?

Only doing resolution for your own domain and dnssec solve pretty much all those issues and is pretty darn easy.

And I did say that the web gui is what you need to lock down, DNS has no vulnerabilities exploitable through port 53 that lets an attacker take control of the server.

You’re saying “If you configure your DNS server properly and understand how it works then it can be setup securely.”

I’m saying “Have you seen the questions in this community???”

… Touché
