One other issue is that MAC addresses are allocated in contiguous blocks to manufacturers. If you know the general pattern (the first N characters are manufacturer-specific), there is precious little stopping you writing a script to loop through all the possibilities and spam the server with them. Most network devices have the MAC address printed on a label (with a barcode for an admin to scan), so it would be trivial to grab an example from a photo.

- yuubi 10y agoSometimes N=9, such as when the address starts 00:50:c2. This block is divided into blocks of 4096 instead of the usual 2^24 so small users can get a block for a few hundred dollars instead of over a thousand.
