Examples

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

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 10, 0, 0, 177 };
byte server[] = { 64, 233, 187, 99 }; // Google

EthernetClient client;

void setup()
{
  Ethernet.begin(mac, ip);
  Serial.begin(9600);
  client.connect(server, 80);
  delay(1000);

  Serial.println("connecting...");

  if (client.connected()) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  } else {
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
  }
}
