type t = {
  1. zones : Domain.Set.t;
    (*

    use this server for these specific domains

    *)
  2. address : Address.t;
  3. timeout_ms : int option;
    (*

    a specific timeout to use for this server in milliseconds

A single upstream DNS server. If zones = [] then the server can handle all queries; otherwise zones is a list of domains that this server should be preferentially queried for. For example if an organisation has a VPN and a special DNS server for the domain `mirage.io` it may want to only send queries for `foo.mirage.io` to this server and avoid leaking internal names by sending queries to public server.
