Eio Unix.EADDRNOTAVAIL on socket bind!?

Thank you this was my issue, connect was to be used here and not bind!!
My original example could be fixed by simply replacing bind with connect:

(* Socket Creation *)
let socket = Unix.socket PF_INET SOCKET_DGRAM 0 in
Unix.setsockopt socket SO_REUSEADDR true;

(* Address Resolution *)
let host_entry = Unix.gethostbyname name in
let entry = Array.get host_entry.h_addr_list 0 in
let addr = Unix.ADDR_INET (entry, port) in

(* Bind socket and address *)
Unix.connect socket addr;

(* Now we can send/recv data *)

The eio example can fixed as follows:

Eio.Switch.run @@ fun sw ->
  let net = Eio.Stdenv.net env in
  let addr = Eio.Net.getaddrinfo_datagram ~service:port net host |> List.hd in
  let sock = Eio.Net.datagram_socket ~sw net `UdpV4 in

  (* Now send/recv data using addr *)
  Eio.Net.send ~dst:addr sock [data_buffer]
