If I am correct, a network interface is the interface between a network interface controller and a network. If I am not correct, please let me know.
How many network interface can a network interface controller have? (My guess: one)
How many network or MAC address can a network interface have? (My guess: one)
My question is from the fact that a computer or a router can have multiple IP or MAC addresses. Does that mean the computer or router
- have multiple network interfaces, each of which has an address, or
- have multiple network interface controllers, each of which has a network interface assigned with an address,
- or both?
Thanks.
