Ethernet : IPAddress class

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 <Ethernet.h>

// network configuration.  gateway and subnet are optional.

 // the media access control (ethernet hardware) address for the shield:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };  
// the router's gateway address:
byte gateway[] = { 10, 0, 0, 1 };
// the subnet:
byte subnet[] = { 255, 255, 0, 0 };

EthernetServer server = EthernetServer(23);

//the IP address is dependent on your network
IPAddress ip(192,168,1,1);

void setup()
{
  // initialize the ethernet device
  Ethernet.begin(mac, ip, gateway, subnet);

  // start listening for clients
  server.begin();
}

void loop()
{
  //print out the IP address
  Serial.println(myIPaddress);
}
