dingo

A DNS client in Go that supports Google DNS(8.8.8.8) over HTTPS.
A DNS client (stub resolver) implemented in Go for the Google DNS-over-HTTPS. It effectively encrypts all your DNS traffic. It also supports OpenResolve by OpenDNS.
The ultimate goal for the project is to provide a secure, caching DNS client that communicates with recursive DNS resolvers over encrypted channels only. For now, it resolves DNS queries over HTTP/2 in independent threads. The plans for future include better caching and support for QUIC.

Quick start

Download a pre-built binary for your platform from the latest release (or build your own binaries).
Run dingo as root on port 53. For example, on Linux:

$ sudo ./dingo-linux-amd64 -port=53

Update your DNS configuration. On Linux, edit your /etc/resolv.conf as root (remember to make backup first), e.g.:

$ sudo sh -c "echo nameserver 127.0.0.1 > /etc/resolv.conf"

Tuning dingo

You will probably want to change the default Google DNS-over-HTTPS server IP address, using the -gdns:server option. First, resolve dns.google.com to IP address, which should give you the server closest to you:

$ host dns.google.com
dns.google.com has address 216.58.209.174
dns.google.com has IPv6 address 2a00:1450:401b:800::200e

Next, pass it to dingo. If you prefer IPv6, enclose the address in brackets, e.g.:

$ sudo ./dingo-linux-amd64 -port=53 -gdns:server=[2a00:1450:401b:800::200e]

To see all options, run dingo -h:

Usage of dingo-linux-amd64:
  -bind string
     IP address to bind to (default "127.0.0.1")
  -dbg int
     debugging level (default 2)
  -gdns:auto
     Google DNS: try to lookup the closest IPv4 server
  -gdns:edns string
     Google DNS: EDNS client subnet (set 0.0.0.0/0 to disable)
  -gdns:host string
     Google DNS: HTTP 'Host' header (real FQDN, encrypted in TLS) (default "dns.google.com")
  -gdns:nopad
     Google DNS: disable random padding
  -gdns:server string
     Google DNS: server address (default "216.58.195.78")
  -gdns:sni string
     Google DNS: SNI string to send (should match server certificate) (default "www.google.com")
  -gdns:workers int
     Google DNS: number of independent workers (default 10)
  -h1
     use HTTPS/1.1 transport
  -odns:host string
     OpenDNS: HTTP 'Host' header (real FQDN, encrypted in TLS) (default "api.openresolve.com")
  -odns:server string
     OpenDNS: web server address (default "67.215.70.81")
  -odns:sni string
     OpenDNS: TLS SNI string to send (unencrypted, must validate as server cert) (default "www.openresolve.com")
  -odns:workers int
     OpenDNS: number of independent workers
  -port int
     listen on port number (default 32000)

Finally, you will need to make dingo start in background each time you boot your machine. In Linux, you might want to use the GNU Screen, which can start processes in background. For example, you might want to add the following line to your /etc/rc.local:

screen -dmS dingo /path/to/bin/dingo -port=53 -gdns:server=[2a00:1450:401b:800::200e]
