Arduino Function: Ethernet.localIp

Description

This function is used to obtains the IP address of the Ethernet shield. It's useful when the address is auto assigned by DHCP.

Syntax

Ethernet.localIP();

Returns

 IP address

Examples

#include 
#include  //if you are using Ethernet Shield 2, use instead 

// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };

// Initialize the Ethernet client library
// with the IP address and port of the server 
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;

void setup() {
  // start the serial library:
  Serial.begin(9600);
  // start the Ethernet connection:
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // no point in carrying on, so do nothing forevermore:
    for(;;)
      ;
  }
  // print your local IP address:
  Serial.println(Ethernet.localIP());

}

void loop() {}
