D-Link shipped NAT-boxes around 2003-2004 or so with identical MAC 
addresses (and a "clone your PC mac address to the WAN 
interface"-functionality). I checked my then employer ADSL network and 5% 
of the customer ports had the same MAC address, D-Link support alledgedly 
said something about the MAC address not being "unique enough" and 
directed their customers to the cloning functionality to "solve" the 
problem.
