You can use a third-party utility to change the MAC of almost any Ethernet adapter - two of them are listed in the external links.

Most consumer-grade routers allow for a user-specified MAC address to be given.

AIX:

Original MAC address:

entstat -d ent1 | grep "Hardware"

Hardware Address: 00:09:6b:be:f8:ed

Using alternate MAC address:

chdev -l ent1 -a use_alt_addr=yes -a alt_addr=0x123456789ABC

ent1 changed

entstat -d ent1 | grep "Hardware"

Hardware Address: 12:34:56:78:9a:bc

Returning original MAC address:

chdev -l ent1 -a use_alt_addr=no

ent1 changed

entstat -d ent1 | grep "Hardware"

Hardware Address: 00:09:6b:be:f8:ed
