How to get my Deno nameserver accessible to the internet?

This is how it's setup:

const socket = Deno.listenDatagram({
  hostname: "127.0.0.1",
  port: 53,
  transport: "udp"
});

const socket = Deno.listenDatagram({
  hostname: "127.0.0.1",
  port: 53,
  transport: "udp"
});

const socket = Deno.listenDatagram({
  hostname: "127.0.0.1",
  port: 53,
  transport: "udp"
});

const socket = Deno.listenDatagram({
  hostname: "127.0.0.1",
  port: 53,
  transport: "udp"
});

I have

ufw enabling and allowing access to all the ports. Not sure what else I'm missing.
