| + | ====== 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 ===== | ||
| + | <code cpp> | ||
| + | #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); | ||
