changing Ethernet MAC address

Can the MAC address be changed to anything other than the {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};

I find that when I change this value to anything else my program doesn't work anymore.

I need to connect 25 Industruino IND I/O based products onto the same LAN network.

As I currently only have one unit available to me I am not able to test if multiple units work on the same LAN.

How do you initialize the ethernet client with this method?

I have checked through the .h files and believe that this part

#define W5500_ETHERNET_SHIELD   // WIZ550io, ioShield series of WIZnet

 

#if defined(W5500_ETHERNET_SHIELD)
#define WIZ550io_WITH_MACADDRESS // Use assigned MAC address of WIZ550io
#include "w5500.h"
#endif

will ensure that the MAC address will be assigned by the WIZ550io.

If this is correct?
