 * @assertion Future<HttpServer> bind(
 *  address,
 *  int port, {
 *  int backlog: 0,
 *  bool v6Only: false,
 *  bool shared: false
 * }).
 * ...
 * The address can either be a String or an InternetAddress. If address is a
 * String, bind will perform a InternetAddress.lookup and use the first value in
 * the list. To listen on the loopback adapter, which will allow only incoming
 * connections from the local host, use the value InternetAddress.loopbackIPv4
 * or InternetAddress.loopbackIPv6. To allow for incoming connection from the
 * network use either one of the values InternetAddress.anyIPv4 or
 * InternetAddress.anyIPv6 to bind to all interfaces or the IP address of a
 * specific interface.
 * @description Checks that if [address]  is a String, then
 * InternetAddress.lookup is performed and the first value in the list is used
