Do routers ports have MAC addresses?
each port on a router has its own mac address, the reason the router has to have seperate MAC addresses, is because each device connected to that router has IT’s own MAC address, so the router will say this packet belongs to the device with XX:XX:XX:XX:XX:XX MAC address, and the routher will pass these frames to and …

Does WIFI and Ethernet have different MAC addresses?
Your MAC address is unique to your computer. On a computer with both a wired and a wireless connection (many laptops and notebooks), there will be one MAC Address for the wired (Ethernet) connection and a second MAC for the wireless connection.
Why do routers use MAC addresses?
A DHCP server (like your router) uses a MAC address to assign an IP address to a network adapter. Without MAC, an adapter can’t get an IP address. Without an IP address, the device can’t connect at all. When this happens within the network, the device will get the same IP address each time it connects.
What are the different types of MAC addresses?
There are three types of MAC addresses: Unicast, Multicast, and Broadcast. The way to identify which address type you are viewing is simply look at the first byte.
What kind of MAC address does a NIC have?

How to determine the MAC address of a network?
A network adapter, also called a N etwork I nterface C ard or NIC, is equipped with a unique identifier known as the M edia A ccess C ontrol (MAC) address. This address can be used by routers and switches to control access to a network. You may find it useful in some situations to determine the MAC address of a NIC in Windows.
How many bits does a MAC address have?
A MAC address has 48 bits and is typically represented as a hexadecimal string, such as 08:00:27:b9:88:74. The MAC address is hard-coded into the NIC by the manufacturer, although modern NICs allow you to change the MAC address programmatically.
How many NICs are there in one computer?
