![]() ![]() ![]() MAC addreess should be unique in a particular network. That is can be done doesn't mean it is a good idea to mess with this. The "official" way of going through the vendor wasn't worth the hassle.įor reasons like the above, most network cards can have their MAC reset in software. Again, the solution was to change the MAC. Some software packages used to be keyed off the network MAC, if that changed, the package supposed to be a pirated copy and refused to work. Again, it was possible to assign MACs at will. As long as the different interfaces were connected to different networks, no one was the wiser. The Sun SPARCstations could have several network cards installed, they all got the same MAC assigned (essentially a machine identifier). If the card broke, it was much easier to get a new one and set it's MAC to the old one's than work your way through the bureaucracy of the ISP. This "address spoofing" was commonly used if you had a machine connected to an external network, not under your control (think early ISP), which registered the MAC address of the machine (really, network card). ![]()
