MAC addresses are of two types, the universally administered addresses assigned by the manufacturer of the NIC and the locally administered addresses which are assigned to a computer device by the network administrator.

That means it can accommodate 2^48 MAC addresses in all. Since, the address is registered and encoded by the manufacturer is it also known as hardware address.
