Thank you!

I am super clear on the mac address now!

Only problem with turning my network administrator over is that he is pushing 300 lb

Thats not true. The real problem is I am at home and don't have a network administrator.

What is this IP? is it the one found in: System preferences / Network / Built in Ethernet / IP address

I have been trying to complete the tutorial found at the below link but I keep getting stuck at this step "Finally, set your Mac address and IP address as normal with this shield."

I have been searching the internet trying to figure out how to determine what IP and MAC address they are talking about and how to find that.

The Ardunio site says that "Newer Arduino Ethernet Shields include a sticker with the device's MAC address. "

My Shield has the following numbers on it's sticker "90-A2-DA-00-2F-E4" problem is this looks nothing like what the program is asking for. The tutorial example looks like
byte mac[] = {  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

So at this point the problem is:

1. What MAC and IP are they asking for?
2. How do I locate them and include them in the code?


My grand plan is to use an Arduino UNO and an Ethernet shield to turn on a series of lights when an "ON" signal is sent from a php script.
