They usually use EEPROM chips to store the addresses nowadays. These
chips have at least 256 bits of storage. 256 bits is 32 bytes which can
hold 5 Ethernet hardware addresses. And you can't buy smaller EEPROMs.
Besides, you only have to store one address and create the rest by adding
1, 2, or 3 to the base address.
