I'm new to this so bear with me :-)

"The Ethernet library requires you to set up a MAC address and the IP address of the server. .... "
I'm confused as to which server are we talking about here?The MySQL server has an IP address?
"It uses Dynamic Host Control Protocol (DHCP) to get an IP address, DNS, and gateway information."
You have to use a IP scanner to get an address every time you want to run a sketch?

" If you want to assign an IP address manually, see the Ethernet.begin() method documentation at
http://arduino.cc/en/Reference/EthernetBegin.";
The example on that page : "Ethernet.begin(mac, ip);" says that ip is the address of the (Ethernet) shield
Shields have an address? I'm confused.
