It comes from the specs, when MAC addresses are used to create an IP 
address.  With this method, the 48 bit MAC address is split into the 24 
bit manufacturer and serial halves and FFFE hex inserted to create a 64 
bit subnet address.  If you have a subnet of any other size, you have to 
use some other method to generate unique local IP addresses.  As I 
mentioned, I have 2^72 addresses.  This is because I have a /56 subnet, 
which is in turn comprised of 256 /64 subnets.
