There is a range of MAC adresses for local use (inside an appliance or even inside a vehicle would be the case). That's what I use for in-lab development on custom MPC855T boards. See for instance <http://www.centsoft.com/mac.htm>. If you don't mass-produce, using the current time for a seed might work. :) HTH -- Albert. ** Sent via the linuxppc-embedded mail list.
