IPAddress(address);

#### Parameters

#### Returns

None

#### Example

#include <SPI.h>
#include <Ethernet.h>
// network configuration. dns server, gateway and subnet are optional.
// the media access control (ethernet hardware) address for the shield:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
// the dns server ip
IPAddress dnServer(192, 168, 0, 1);
// the router's gateway address:
IPAddress gateway(192, 168, 0, 1);
// the subnet:
IPAddress subnet(255, 255, 255, 0);
//the IP address is dependent on your network
IPAddress ip(192, 168, 0, 2);
void setup() {
Serial.begin(9600);
// initialize the ethernet device
Ethernet.begin(mac, ip, dnServer, gateway, subnet);
//print out the IP address
Serial.print("IP = ");
Serial.println(Ethernet.localIP());
}
