you are not informed then. To suggest this is not an appropriate topic is simply ignorance. There are many legitimate reasons for cloning a MAC address. I will mention but a few.
Legitimate uses of MAC spoofing
An example of a legitimate use of MAC spoofing is hanging the function of a single computer from a router to computer and back to router through MAC spoofing. If you only have a single public IP, you can only hook up one unit
directly (PC or router). If one has two WAN IPs, the MAC address of the two devices must be different. For whatever reason, if one needs to swap 2 PC's regularly to connect to the cable modem, it would be a lot easier to change the MAC addresses rather than to change the Network Interface Card (NIC). Many cable modem routers have a "Clone MAC Address" feature built-in for this. (In reality, the easiest way to enable two machines to access the same ISP from the same location is to use a cable modem router like LinkSys, which allows multiple MACs to use a single ISP connection.)
