Why router needs mac address?
the tcp/ip frame uses the ip address to send messages between devices (computers, printers, etc) on your network. This frame is inside an ethernet frame on the network layer. The ethernet layer does not use ip addresses at all, they use mac addresses. For an ethernet frame to travel through a router, it needs a mac address. Your router actually does not need an ip address. It will respond to broadcasts. In fact sometimes it won't answer to tcp/ip requests. Its job is to deliver the datagram to its destination more than it is to answer you (your computer that is). So sometimes a router will not answer a ping, but a computer on the other side of the router will answer even if there are several router in the path.
