I wrote a super basic DNS server in go (mostly fun and go practice) which allows you to specify hosts and ips in a json config file. This eliminates the need for editing your /etc/hosts file. If it matches a host in the json config file it returns that ip, else uses Cloudflare public DNS resolver as a fallback. Please; easy on my go code :-). I am a total beginner with go.
