 With the exception of **[LPT] Parallel Port Internet Protocol**, every emulated network card stores its MAC address in the ``mac`` directive of its respective configuration file section. Only the suffix (last three octets) of the MAC address can be edited; the prefix (first three octets) will always be the card manufacturer's `Organizationally Unique Identifier <https://en.wikipedia.org/wiki/Organizationally_unique_identifier>`_, such as 00:E0:4C for Realtek.
