Is there a difference between the MAC address of a NIC and a microcomputer?

The first three digits of MAC address represent the manufacturer, not the device (e.g., network card, smart switch, router, etc.).

It's not the same. The MAC address of any 2 devices is different. But the format is the same.

In layman's terms, a MAC address is the house number of a computer, and each one is unique in the network.

If you surf the Internet through a router, the MAC address of the router is like the house number of the community. The subnet established by the router assigns its own house number to the residents of the community. The MAC address of the subnet is not recognized by the external network, and the MAC address of the router is used to connect to the external network.

The Medium Media Access Control (MAC) address is an identifier used to represent every site on the Internet, in hexadecimal numbers, with a total of six bytes (48 bits). Among them, the first three bytes are assigned by the IEEE's registry RA, which is responsible for assigning ** (high-level 24-bit) to different vendors, also known as "organizationally unique identifiers", and the last three bytes (low-level 24-bit) are assigned by each vendor to the production adapter interface, which is called extended identifier (uniqueness). A single address block can generate 224 different addresses.

The MAC address is actually the adapter address or adapter identifier EUI-48.

Yes, the principle is actually the same, they are all physical addresses, used for layer 2 communication, you can connect to the computer after setting up the router, and the community has nothing to do with it, it can only control the WAN port of your router, and the network inside your router is not clear.

It's not the same. The MAC address of your current computer is for you to use to surf the Internet.

If you use wireless routing. Just set the MAC address in your wireless router. Set a password.

The IP of the computer can be set to automatically obtain the IP.

It's simple, as long as there is an option on your router"Clone your local Mac"Apply it, enter a fixed IP on the Internet mode, and the method is as follows:1Do not connect the router to the network before operation, 2 first let your computer go to the Internet normally, and then unplug the network cable that surfs the Internet, 3

Use your computer to configure this router, at this time, you can't connect the line to the WAN port, configure the router, mainly"Clone your local Mac"After the configuration is completed, save it, make sure that the settings have been completed, and then connect the Internet line to the WAN port, and try it. Hehe, it's best not to let your network administrator know about this matter first, and if it really doesn't work, then ask the network administrator for help.

The MAC address of a router is the same as the MAC address of a computer.

The principle is basically the same, yes, you can access the Internet.

MAC English Media Access Control or Medium Access Control, transliterated as **Access Control.

The MAC address is determined by the NIC and is fixed.

In the OSI model, the third layer network layer is responsible for IP addresses, and the second layer is responsible for MAC addresses.

So a host will have a MAC address, and each network location will have an IP address that is unique to it.

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.

In the physical transmission process at the bottom of the network, the host is identified by the physical address, which must be unique in the world.

The physical address is an encoding that is programmed on a network interface card (NIC). In the LAN (Local Area Network) of Ethernet, this code is called the MAC address.

The mac address is the English name of the physical address! It makes no difference.

The two are the same, but they are called differently.

The MAC address of the router is the physical address of the network adapter in the router.

The MAC (Media Access Control or Medium Access Control) address, which is translated as access control, or physical address or hardware address, is used to define the location of network devices.

Each network adapter has a MAC address.

It's the physical address of your router port, the MAC address is unique in the world, and you can't tell what your router MAC address is if you ask someone like this. Please check the router manual and the label on the back of the router yourself, it should be written on it. Note that the router should have 2 MAC addresses, which are LAN and WAN, make no mistake.

You can also log in to the router management page.

Answer: "Router MAC means the physical address of the network card; 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 route 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.

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" in the command line and get the following information.

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.

What do you mean by MAC address in the router?,That's an address that the router automatically generates for each device connected to the wireless.,An address composed of English letters、Numbers and horizontal bars,For example, B2-30-15-20-7,This is used to help you use the MAC address filtering function。

The MAC address 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 route 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 now, this address is not fixed for every computer.

Run arp -a

If you find the IP address of the route, the corresponding physical address is the physical address of the route LAN buckle.

Log in to the router to view the operation, or LAN port settings.

It's not just Apple's notebook.

All NICs have one and only one MAC address. The MAC address is written as the NIC chip is produced.

Although it can be rewritten with software, it is not recommended. There are two MAC addresses in one broadcast domain, and both network cards cannot connect to the network.

Most computers have different Ethernet Mac Address and WiFi Mac Address, because they belong to different network cards, and each network card will have a Mac address
