@Override
  public String toString() {
    return inetSocketAddress.toString();
  }
Returns an InetSocketAddress for this host and port. An attempt is made to resolve the
host name but if resolution fails an unresolved InetSocketAddress is returned. This return
value will not hold an InetAddress, so calling getAddress() on it will return null.
