This is simple dns server that forwards requests to google's http based dns server.
It's based on the example dns forwarder in https://github.com/mirage/ocaml-dns
It's quite crashy
opam install lwt
opam install dns
opam install cohttp
opam install tls
opam install ppx_deriving_yojson
make
sudo ./dns_forwarder
$ nslookup google.com 127.0.0.1
