Locally Administered MAC Address
The Locally Administered MAC Address is used to override the “burned-in” address of network interface cards (NICs). The Locally Administered MAC Address is a user-defined MAC address that is used in place of the MAC address originally assigned to the network adapter. Every adapter in the network must have its own unique MAC address. This locally administered address consists of a 12-digit hexadecimal number.
The appropriate assigned ranges and exceptions for the locally administered address include the following:
The range is 00:00:00:00:00:01 to FF:FF:FF:FF:FF:FD.
Do not use a multicast address (least significant bit of the high byte = 1).
Do not use all 0s or all F’s.
Creating An Access Point With A Locally Administered MAC Address
Using airbase-ng we can create an Access Point with a locally administered MAC address.
root@bt:~# airbase-ng -e “SSID” -a 00:00:00:00:00:01 wlan0
For information, no action required: Using gettimeofday() instead of /dev/rtc
