nameserver_of_string authenticators str returns a Transport.io_addr from the given string. The format is:

  • udp:<ipaddr>(:port)? for a plain nameserver and we will communicate with it via the UDP protocol
  • tcp:<ipaddr>(:port)? for a plain nameserver and we will communicate with it via the TCP protocol
  • tls:<ipaddr>(:port)?((!hostname)?!authenticator)? for a nameserver and we will communicate with it via the TCP protocol plus the TLS encrypted layer. The user can verify the nameserver via an authenticator (see X509.Authenticator.of_string for the format of it). The hostname can be provided to be used as peer name by the authenticator. By default, Ca_certs_nss.authenticator is used.
val connect : ?cache_size:int -> ?edns:[ `None | `Auto | `Manual of Dns.Edns.t ] -> ?nameservers:string list -> ?timeout:int64 -> Transport.stack -> t Lwt.t

connect ?cache_size ?edns ?nameservers ?timeout (stack, happy_eyeballs) creates a DNS entity which is able to resolve domain-name. It expects few optional arguments:

  • cache_size the size of the LRU cache,
  • edns the behaviour of whether or not to send edns in queries,
  • nameservers a list of nameservers used to resolve domain-names,
  • timeout (in nanoseconds), passed to create.

The provided happy_eyeballs will use t for resolving hostnames.
