Example

This example shows how to set the Google DNS (8.8.8.8). You can set it as an object IPAddress.

#include <SPI.h>
#include <WiFi.h>
// the IP address for the shield:
IPAddress dns(8, 8, 8, 8);  //Google dns
char ssid[] = "yourNetwork";    // your network SSID (name)
char pass[] = "secretPassword"; // your network password (use for WPA, or use as key for WEP)
int status = WL_IDLE_STATUS;
void setup()
{
  // Initialize serial and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
  Serial.println("WiFi shield not present");
  while(true);  // don't continue
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
  Serial.print("Attempting to connect to SSID: ");
  Serial.println(ssid);
  // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
  status = WiFi.begin(ssid, pass);
  // wait 10 seconds for connection:
  delay(10000);
}
  // print your WiFi shield's IP address:
  WiFi.setDNS(dns);
  Serial.print("Dns configured.");
}
void loop () {
}
