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?

    Use a public dns provider. Cloudflare, route53, dyndns (are they still around?), etc. Cheap, reliable, no worries about joining a ddos by accident. Some services are better left to experts until you really know what you’re doing.

    And if you do really know what you’re doing you’ll use a dns provider rather than host your own.

      Cloudflare is not private… not sure if dyndns has even worse reputation than cloudflare

      Some services are better left to experts until you really know what you’re doing.

      DNS, for experts? 😂

      You host your own dns, and don’t work with glowing services, this is the private way

        Host your own private DNS - yes, knock yourself out. I highly recommend it.

        Public DNS? No - don’t do that.

        There are two services homegamers should be extra cautious of and should likely leave alone - DNS and email. These protocols are rife with historic issues that affect everybody, not just the hosting system. A poorly configured DNS server can participate in a DDOS attack without being “hacked” specifically. A poorly configured mail server can be responsible for sending millions of spam emails.

        For a homegamer you probably only need a single public DNS record anyway (with multiple CNAME if you want to do host based routing on a load balancer). You take on a lot of risk with almost zero benefit.

          You don’t knock yourself out, it doesn’t look like you ever even tried it

          See you when you start selfhosting stuff, or at least get interested

          Also, knocking yourself out is not privacy, but anonymity 🤭

            Uh oh - my “nerd creds” are being questioned by a rando on the internet. 🤣
