WiFi.setDNS() allows you to configure the DNS (Domain Name System) server.
WiFi.setDNS(dns_server1)
WiFi.setDNS(dns_server1, dns_server2)
dns_server1: the IP address of the primary DNS server
dns_server2: the IP address of the secondary DNS server
Nothing
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 <WiFi101.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

Serial.print
