The router responds, “I have IP address 192.168.1.1 and I see that you’re calling from 192.168.1.2 so I’ll forward all data packets to your physical MAC address 01:23:45:67:89:AB. “Please tell 192.168.1.2” (tell me, the laptop, because I’m trying to send/receive data). The laptop says “who has IP address 192.168.1.1”? (which is the routers IP address). This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
But since you don’t want them knowing where your home is located, you tell the operator (the router), that you’re expecting a package and that when it arrives, to send it to your physical Address (the MAC address).įrom a technical viewpoint, it looks more like this: A media access control address ( MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. The person trying to reach you is trying to deliver a package to your home address (in this case, the package is a data packet). The operator (router) receives a call for you and forwards the call (using the ARP protocol) to your home phone number (your private IP address). You have a physical home address located at 123 Main St, Somewhere, USA (let’s say this is your computers MAC address). You have a private home phone number (your private IP address). The telephone operator is, let’s say, your NAT server (router). Once again, let’s use the address and telephone number example to break this down into a digestible example: TIP: ARP may sound similar to a Network Address Translation (NAT), but you need to understand that NAT is used for addressing and locating networks whereas, ARP is used to deliver the actual data to the physical device. Once the request reaches the correct network using the IP address, ARP is what converts an IP address to a MAC address and delivers the data packet to the right computer. The IP address is what is first used to find the right network. So, the router sends a broadcast that says “hey everyone, if you have IP address X, please tell me what your MAC address is.” One of your computers will respond “Hello, I have IP address X and my MAC address is XYZ, please forward the data to my MAC address.” Your router is basically trying to resolve (find) the physical address of which computer this IP address belongs to. So, the router sends an ARP broadcast request on the LAN. When you router wants to send data packets to your computer with IP address ‘X’, the router needs to know what your computers MAC address is. If your computer has two Ethernet ports and dual-band wireless, it will have four MAC addresses. If it has dual-band wireless capability, it will have a MAC address for each wireless band. If the computer has two Ethernet ports, it will have a MAC address for each Ethernet port. Each network controller has its own MAC address. Locate the adapter you’d like to find the MAC address for, then click the link beside “Connections.” The link will vary depending on connection type, but will typically read “Ethernet” or “Wi-Fi.In the previous image, I have one Etherent controller, and one wireless controller. The MAC Address is a six-byte number or 12-digit hexadecimal number that is used to uniquely identify a host on a network. In Network and Sharing center, you’ll see a list of your active network connections. Every NIC (Network Interface Card) has a unique MAC address (Media Access Control).This applies to all types of network cards, including Ethernet cards and WiFi cards. To get started, launch Control Panel, then click “View Network Status and Tasks.” #NETWORK CARD MAC ADDRESS ON A MAC WINDOWS 10#
The Control Panel utility in Windows 10 or Windows 11 also lets you locate your network adapter MAC addresses, but it takes a few more clicks than the Settings app.

If necessary, you can select and copy the MAC address (Ctrl+c) and paste it (Ctrl+v) to a text file or a messaging app. You’ll see the MAC address listed beside “Physical Address (MAC).” For example, the MAC address here is “2b:fc:f3:f3:f3:2b”. Locate the adapter you want to find the MAC address for in the list (such as “Wireless Network Adapter” for your Wi-Fi connection). In Hardware and Connection Properties, you’ll see a list of information about every network adapter installed on your PC. In Network & Internet settings on Windows 11, click “Advanced Network Settings,” and then select “Hardware and Connection Properties.”
