"Private" MAC Addresses

[Michael Jeung]

Hi folks,

I'm interested in assigning a bunch of virtual MAC addresses on my  
network but I want to make sure that I'm not conflicting with MAC  
addresses that are already out there.

(I've already taken a look at this nice resource: http:// 
www.cavebear.com/CaveBear/Ethernet/vendor.html)

Are there any MAC address ranges which are reserved as private?  I'm  
talking about an equivalent to the 10.0.0.0/8, 192.168.0.0/26 and  
172.16.0.0 ranges for IP addresses - basically a range of MAC  
addresses that I can use without fear that it'll interfere with some  
future network device.

Thanks,
Michael Jeung
