IPAddress()
Description
Defines an IP address. It can be used to declare both local and remote addresses.
Syntax
IPAddress(address);
Parameters
address: a comma delimited list representing the address (4 bytes, ex. 192, 168, 1, 1)
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()); } void loop() { }
