Answer from AI
In theory, there are $2^{48}$ unique MAC addresses, which is approximately $2.81 \times 10^{14}$.
In practice, the number of MAC addresses used is limited by network device manufacturers (EUI-48 standard), each of which is assigned a range of addresses.
In a specific system (for example, a computer), there may be several MAC addresses, one for each network interface:
- Ethernet port
- Wi-Fi adapter
- Bluetooth adapter
- Virtual network interfaces (for virtual machines, VPNs, etc.)
Thus, the number of MAC addresses in a system depends on the number and type of installed network adapters.
