Ping a DNS that is almost up Like 4.2.2.4,4.2.2.3,4.2.2.2

Ping myPing = new Ping();
String host = "4.2.2.4;
byte[] buffer = new byte[32];
int timeout = 1000;
PingOptions pingOptions = new PingOptions();
PingReply reply = myPing.Send(host, timeout, buffer, pingOptions);
if (reply.Status == IPStatus.Success {
  // presumably online
}
