+ Repeating Web client
+
+ This sketch connects to a a web server and makes a request
+ using a Wiznet Ethernet shield. You can use the Arduino Ethernet shield, or
+ the Adafruit Ethernet shield, either one will work, as long as it's got
+ a Wiznet Ethernet module on board.
+
+ This example uses DNS, by assigning the Ethernet client with a MAC address,
+ IP address, and DNS address.
+
+ Circuit:
+ * Ethernet shield attached to pins 10, 11, 12, 13
