[LUG] MAc address changing was Re: MAC address on Android

[Tom <madtom1999@xxxxxxxxxxxxxx>]

In the early days your MAC address was hardwired into the 'ethernet' 
card by the manufacturer. You could normally only send IP stuff out 
through the hardware and the MAC address was automatically put into the 
data packet by the hardware. You could buy a more expensive card that 
allowed you to send out the the IP stuff where the MAC address was 
software controlled - this allowed you to host lots of IP addresses from 
one ethernet port. But these cards were several times the cost of 
hardware controlled cards.
Obviously they can be picked up in skips now so if someone was spoofing 
your MAC address this was how they was doing it.
For a phone (or Android device) to change it's MAC address on reboot 
requires a full refund.
