The MAC address, as given by "ifconfig" "HWaddr" should be the same on
each reboot.
MAC address can also be displayed with "ip a"

It is possible for software to change it.
If there is a bug in the ethernet driver or a corrupted eeprom, it
might try to behave differently.

Which hardware is the nic card?
lspci -v
lspci -vnn

If you wish to fix it to a particular address, you can use the
"ifconfig" to set it to a fixed value in one of the network init
scripts.

Kind Regards
