Questions & Help Questions

Are there any libs to work with DNS wire format ? I found this lib for erlang not sure how to work with this though

https://github.com/lateio/dnslib

anyone experienced with the format got some questions, working on a side project

I have this code where I can read the incoming application/dns-message body of the request

echo -n 'q80BAAABAAAAAAAAA3d3dwdleGFtcGxlA2NvbQAAAQAB' | base64 | curl -H 'content-type: application/dns-message' --data-binary @- https://cloudflare-dns.com/dns-query -o -

 post "/" do
    {:ok, body, conn} = Plug.Conn.read_body(conn)

    {:ok, query} = String.trim(body) |> Base.url_decode64(padding: false)

    IO.inspect(query, label: "Query")

    conn
    |> put_resp_content_type("application/dns-message")
    |> send_resp(
      200,
      Jason.encode!(%{
        msg: "I don't have a heart but I am alive!"
      })
    )
  end

i am trying to work this out Using DNS Wireformat

Not sure how to make a request to the upstream DNS from wireformat and return a response I am using GitHub - tungd/elixir-dns: DNS library for Elixir · GitHub to do the JSON format. Need to know how to get the wireformat to standard domain to send using elixir-dns and then convert the response back to wireformat
