What do these two sets of MAC IP addresses represent in the router settings?

1. The MAC address of the LAN port refers to the MAC address of the network port connected to your LAN on the router, while the WAN port refers to the MAC address of the network port that demodulates the modem. Because the router is ** (or NAT) translation, it must have at least 2 network ports, one connected to the external network (WAN) and one connected to the local area network (LAN), so what you see is 2 MAC addresses. The MAC address is unique to both the computer network card and the router network card. , is the internationally prescribed IP address for LAN, which is the intranet address assigned by the router by default and acts as the gateway for your LAN PC. Namely:

Your computer (assuming that the IP is: when surfing the Internet, the data packet is first sent to the internal network port of the router), which is converted by the router and sent out from the WAN port.

3. You understand it very correctly, that is, it belongs to the "world's only" kind of IP, which is assigned by the operator to the WAN port of the router.

4. Needless to say, you understand it very correctly.

1. The MAC addresses of the two MACs are the LAN port and the WAN port, both of which belong to the router, but the ports are different.

The 168 network segment is the intranet segment, which can only be used within the LAN, and the LAN port of the general router is the default internal IP address, and the communication with the external network should be converted into the internal IP through the WAN port (here.

3. Yes, this is assigned to the router, although the IP you connect to the router is the network segment, it must be converted into this address to communicate with the outside world.

4. You're smart.

First of all, you think of a router as a computer with 2 network cards, and one network card is connected to the ADSL cat, which we call WAN.

The other network card connects to your computer or switch, we call it LAN, and that's the answer to the first question. In addition, there is no exact same MAC address in the world, just like the ID card of the network card.

2. This is the default IP address of the router's LAN port.

3. The only one in the world, yes. It is assigned by your ISP, which is the company you handle the broadband.

4. That's right.

1. The MAC is a network card, which cannot be repeated.

2. This is the intranet IP of the router and the gateway of the intranet, which can also be changed.

3. This is the only public IP in the world, which is the only one in the world, which is public to the router.

4. Yes, this is the IP of the intranet, as long as there is no same in the same LAN.

The MAC is the physical address of the NIC.

It is different from an IP address, which is used to indicate the location of a computer on the global Internet, while a MAC address is used for routing calculations to find the nearest path. The MAC address of the network card varies around the world, and each network card has only one MAC address. However, the MAC address of the network card can be changed.

So Lingyuanshan is now not fixed for every computer.

Settings: 1. Enter the ms-dos command line. The method is to click "Start" - >Run" on the taskbar, enter "cmd" after "Open" in the "Run" dialog box, and enter the MS-DOS black screen after confirmation.

2. Outsmart the IP address and MAC address of the public Internet computer. Enter "ipconfig all" on the command line to get the information shown below.

3. Change the MAC address of your computer. First, select Network Connections on the Desktop or Control Panel, right-click the corresponding NIC, select Properties, and click the Configure button on the General page of the property page.

In the configuration property page, select "Advanced", then select "Network Address" in the "Properties" column, select the "Input" box in the "Value" column, and then enter the MAC address of the person just now in the "Input" box.

4. Change the IP address of your computer. As shown in the figure below.

What does the MAC address of the current management PC in the router mean? How do I fill in my mac address.

Dear I'm glad to answer for you, my mu yuan answer is as follows: The MAC address of the current management PC in the router is:The MAC address of the current management PC, which refers to the network card ID number of the computer you are now using to log in to the router, and the MAC address is filled in to refer to the network card ID number of the wide computer that you are now using to log in to the router. Extend the MAC is the ID card number of the NIC, and the IP address is the residential address of the NIC, and the residential address may be numbered, but the ID number will never change.

If you manage the router, you must use a computer or mobile phone, so the current management of the MAC address of the PC means that you are now using the network card ID number of the computer that logs in to the router As for the function, if you generally know the MAC address, you can set up a static route on the router, which is to bind the MAC address to a fixed IP, which can reduce the loss of the router and save time each time you reassign the IP (mainly when there are hundreds of computers in the enterprise, especially when you just go to work in the morning, Hundreds of computers are turned on at the same time, and the router will be very tired when assigning IPs), in addition, if you want to set certain restrictions on the router, such as network speed restrictions, such as restricting access to certain web pages, etc., you need a Mac, and you can wake up the computer remotely.

The MAC address of the router is the unique identifier of the router, which is equivalent to its ID in the network world, sometimes we may use the MAC address, so how to check the MAC address of the router, let's talk about it;

Routers, computers.

01 Generally, there will be a label at the bottom of the router, and the main information is the management address and MAC address of the router, which we will record here;

02 Enter the management address in the browser, you need to enter the administrator password to log in to the management page, at this time, pay attention to the MAC address at the bottom right of the page, and the address at the bottom of the router is a little different, what is going on;

03 Enter the administrator password, log in to the management page, and see that the MAC address below is the same as just now, let's go one step further and click Advanced Settings;

04 Enter the advanced settings page, the system status page has two MAC addresses, one is the WAN port, the other is the LAN port, which can be understood as an input and an output, it seems that the MAC address of the WAN port seen earlier, so which one we need;

05 Open "Command Prompt" in the start menu, or "Win+R" to open and run, enter cmd to open "Command Prompt";

06 Enter "arp", press enter, you can see that -a and -g can see the physical address (mac address), let's try it below;

07 Enter "arp -a", press enter, the physical address appears, and the MAC address of the LAN port is displayed here, then we will take this as the standard.

Before checking the MAC address, make sure that the computer is connected to the router you want to view.

The router MAC is the NIC address of the client, and each hall hides a site identifier, which is represented by hexadecimal numbers. The MAC network card address is the unique address of the matching computer, which is directly burned into the network chip in the device through photolithography. Today's routers have the function of cloning addresses, and you can access the Internet when you turn it on.

Router MAC can be connected to computers, mobile phones, tablets and other devices, collectively known as the client's network card source address, is used to represent the Internet, the identification symbol of each site, using hexadecimal numbers.

The MAC network card address is the unique address that matches the computer, and it is directly burned into the network chip in the device through photolithography, and the address cannot be modified, but some operating systems can customize the fake MAC address. Hail.

MAC address binding is to bind the network card address of the computer host, so that the address of other computer network cards can not access the Internet, and now routers have the function of cloning the address, access the computer from the external network, and after obtaining the address, you can access the Internet.
