Asus RT-AC68U
Kong v3.0-r38100M kongac 12/27/18

The 2.4 interface (eth1) has a MAC address AC:9E:17:xx:yy:EA

If I create a virtual interface wl0.1 on the same radio and apply settings, it gets a MAC address of AE:9E:17:xx:yy:EB

Is it a bug that the first byte changes from AC to AE? This does not sound right to me. If I do a OUI search, AE:9E:17 prefix is not even registered!

Nevermind, this answer clarifies it:
https://serverfault.com/questions/40712/what-range-of-mac-addresses-can-i-safely-use-for-my-virtual-machines

Quote:

There are actually 4 sets of Locally Administered Address Ranges that can be used on your network without fear of conflict, assuming no one else has assigned these on your network:

x2-xx-xx-xx-xx-xx
x6-xx-xx-xx-xx-xx
xA-xx-xx-xx-xx-xx
xE-xx-xx-xx-xx-xx

Replacing x with any hex value.


So AE: would be a valid locally administered prefix.
