Tips

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

So,

1. No cache. use it as a backend, dnsmasq or unbound as frontend, or fwdns
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.
