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.

connect ?cache_size ?edns ?nameservers ?timeout stack 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

raises [Invalid_argument]
if given strings don't respect formats explained by nameserver_of_string.
