DNS Over HTTP/2

DNS Over HTTP/2

EXPERIMENTAL only

For original development version see:

https://github.com/Opensourcecommunitydevelopment/dns-over-http2

For original version see:

https://github.com/yyfrankyy/dns-over-http2

Inspired by gdns-go, but do less, I'd like to keep it as simple as possible.

So,

1. No cache. use it as a backend, dnsmasq or unbound as frontend.
2. No proxy. setup your proxy globally, the script will simply honor it.
3. Less config. if your public ip is changed, restart the script.

Last but not least, long live process, I prefer pm2.

Write a process file with your customized setup (say dns-over-http2.json):

{
  "apps" : [{
    "name"        : "dns-over-http2",
    "script"      : "/path/to/your/dns-over-http2/index.js",
    "args"        : ["your public ip", 6666, "127.0.0.1"],
    "env": {
        "NODE_ENV": "production"
    }
  }]
}

Simply start it as follow:

pm2 start dns-over-http2.json

All set, test it with dig:

$ dig @127.0.0.1 -p 6666 github.com A +short
github.com.
192.30.253.112

dns-over-http2's Issues

What's are the arg parameters in dns-over-http2.json?

Is this the way it's set up? Do we need a forwarding DNS server or external IP?

{
  "apps" : [{
    "name"        : "dns-over-http2",
    "script"      : "~/Workspaces/GIT-Projects/dns-over-http2/index.js",
    "args"        : ["**external IP address** or **forwarding name servers**", 
                        port, 
                       "local dns-over-http2 server address"],
    "env": {
        "NODE_ENV": "production"
    }
  }]
}

'use strict' is required for my setup

It seems I have to use

'strict mode';

If I add 'strict mode' the code now runs but I'm confused about the parameters in dns-over-http2.json.
