The physical address is the address of your network card, and the MAC (Media Access Control) address is the identifier that identifies the LAN (Local Area Network) node. The physical address of a network card is usually the EPROM (a flash memory chip, usually written by a program) burned into the network card by the network card manufacturer, which stores the addresses of the computer that really identifies the computer that sent the data and the host that received the data when transmitting data.
That is to say, in the physical transmission process at the bottom of the network, the host is identified by the physical address, which is generally unique in the world. For example, the physical address of a well-known Ethernet card is an integer of 48 bits (bits), such as: 44-45-53-54-00-00, which is stored in a machine-readable way into the host interface.
The Ethernet Address Management Authority (IEEE) divides Ethernet addresses, that is, different combinations of 48 bits, into several independent contiguous address groups, and manufacturers who produce Ethernet network cards purchase one of them, and give unique addresses to Ethernet cards one by one during specific production.
Figuratively speaking, the MAC address is like the ID number on our ID card, which is globally unique.
You can get the MAC address like this: in Windows 98 ME, click "Start" "Run" and enter "WinIPCFG" Enter. You can see the MAC address.
In Windows 2000 XP, click Start Run Enter cmd Enter Enter IPCONFIG ALL Enter. You can see the MAC address.

It refers to the practical, logical correspondence.

You are familiar with the IP address, every computer has an IP, but it is not unique, it can be changed through settings.
A computer network card corresponds to a physical address, so for a computer, the physical address is its only network symbol and cannot be changed.
1.Turn on the Run button.
2.In the Run dialog box, enter cmd and click OK.
3.In the command prompt, enter ipconfig -all.
4.Press the enter key to view the physical address.

Some friends may have heard the term physical blind address, but don't know what it means. Today, I will tell you what is a physical address, how to check the physical address of your computer, and the following operations are all operated on the win10 system.
A physical address is an identifier that is used to mark every device in the network, just like we usually send and pick up a courier, and all the data in the network will contain the physical addresses of the sender and receiver.
First we press on the keyboard"win+r"key, open"Run"Window;
Enter in the Run window"cmd"and press back to the wide round cart;
In the open"Command prompt"window"ipconfig-all";
After pressing enter, we will be able to see the physical address of our computer.
in memory. In order to store or retrieve information correctly, each byte unit is given a unique memory address, called a physical address, also known as an actual address or an absolute address.
The IP address is the address you need to use to surf the Internet, and the physical address is the address of your device, which is unique in the world. >>>More

The IP address is a network address, which can be changed. You can choose to automatically assign corner modifications. If the computer does not change the network much (such as frequent mobile office) there is no harm, the big deal is to change back to let the dynamic allocation be, but the IP modification must be in this network segment, otherwise it is not possible to access the Internet.
If the "Local Connection" display status changes to "Restricted or No Connection" for no reason, this is usually due to the fact that the NIC is not assigned a fixed IP address. Under normal circumstances, when we find that the display status of "Local Connection" is abnormal, we can often try to set a static IP address for the network connection first, which can often solve many inexplicable network failures for us. Once we find that the local network connection does not use a fixed IP address, we can click the "Start" "Settings" and "Network Connection" commands in turn, and then in the network connection list interface, right-click the "Local Connection" icon with the mouse, and execute the "Properties" command from the right-click menu to open the property setting window of the local connection; In the "General" tab page of the window, select the "Internet Protocol" item and click the "Properties" button once. >>>More
