Apple 4S, what does MAC address mean?

The MAC address is the unique identifier of the device and is written inside the hardware by the network equipment manufacturer. As long as the MAC address is not changed, it is globally unique.

IP addresses are used to confirm the location of network devices. In the OSI model, the third network layer is responsible for processing IP addresses, while the second layer data link layer is responsible for processing MAC addresses. The MAC address is used to uniquely identify the network card in the network. If the device has multiple network cards, each network card will have a unique MAC address.

Enter the phone settings, click "System", then click "About Phone", and finally find "Status Message".

The MAC address is the physical network address used to identify the link layer address in the network world. In a network, the network card of each device has a unique MAC address, and the IP address is used to identify the host in the network. When we access a host on the network, communication is actually achieved by converting the IP address of the target host into the corresponding MAC address through the ARP protocol. In short, there is a one-to-one correspondence between MAC addresses and IP addresses. Address translation is achieved through the ARP protocol, allowing us to smoothly access other hosts on the network.

The MAC address is determined by the network card and is fixed. The same goes for the iPhone, which also has a unique MAC address.
