FIND OUT WHAST A DEVICE IS ON NETWORK MAC ADDRESS MAC
So security teams around the world construct corporate firewalls that only allow specific MAC addresses in. The answer is yes!įor example, since MAC addresses are permanently assigned to all network devices, they are also a great way to filter out unwanted devices from your network. You might wonder if there are any other benefits to MAC addresses besides enabling IP addresses. And without an IP address, your device won’t connect to the outside network at all. To assign an IP address in the first place, your router will use your device’s MAC address. IP addresses can venture out of the same network by using a router.īut you can’t just rely on IP addresses. MAC addresses function on a low level between devices on the same network. So what’s the difference?īoth MAC and IP are critical to any network, and they work well together. When you just learn about MAC addresses, it can be difficult to differentiate them from IP addresses, which more people are familiar with. How is a MAC address and IP address different? Sometimes, certain companies choose to assign similar MAC string combinations to their devices, so they can easily find device by MAC address if need be. The rules by which MAC addresses are created is managed by the IEEE (Institute of Electrical and Electronic Engineers). So a MAC address example could be something like 21-22-EJ-8C-D2-99. They can be upper or lowercase (although not mixed), and divided by colons, dashes, or written together. For any devices to communicate, one must send information to another’s MAC address.Ī MAC address is a string of six two-character combinations (both numbers and letters). But why?Įssentially, what a MAC address does is manage the NIC (network interface controller), or network adapter, that you need to connect to any network, be it Ethernet, WiFi, or Bluetooth. What Is A MAC Address Exactly?Įvery network-connected device has a unique MAC address assigned by its manufacturer. *Note for laptop users: If you do not have "Ethernet Adapter Local Area Connection", please look under "Ethernet adapter Wireless Network Connection." However, if you use the Physical Address under the Wireless Network Connection and turn off or disable your wireless card or device, the product may not function until it is re-enabled.So what is a MAC address exactly? How is it used? How do you locate it? Can you be traced through it? Can you change it? Let’s explore these and other questions in our comprehensive MAC address guide. Under the Ethernet Adapter Local Area Connection section, look for the “Physical Address”. In the Command Prompt window, type ipconfig /all and Press Enter. Click on the Start Menu, then select Run.
