The MAC Address and other parameters will be displayed in the DOS window.At the prompt, type the following: ipconfig /all.This number is often imprinted on the network card however, you may query your computer for the number, using one of the following methods: This is called MAC filtering.The Ethernet MAC Address is a unique identifier for network cards, of the form 05-A8-34-C3-67-B4 or 05A8342367B4 (6 pairs of digits and characters in the range A-F, which might or might not be separated by hyphens). In addition to sending your data to the right place, your wireless router also uses MAC addresses to secure your connection by only accepting traffic from devices with MAC addresses that it recognizes. Ethernet: How Much Better Is a Wired Connection? How Are MAC Addresses Used? If your laptop has an ethernet port and Wi-Fi, for example, it would have different MAC addresses for the Wi-Fi connection and the Ethernet connection. Your router tracks outbound data requests so that when the data comes back, it can attach the correct private IP to the data packets, then send them along to whichever device’s MAC address matches that private IP.ĭevices can have more than one MAC address because they get one for every place they can connect to the internet.
This is different from the IP address your internet service provider (ISP) assigns you-that’s your public IP address. It does this using MAC addresses, assigning a private IP address to each network-connected device based on that device’s MAC address.

MAC addresses are used to identify which device is which on your local network so that data gets sent to your computer and not your roommate’s smartphone.

Hardware devices like routers and cables transmit the data we need, while software like border gateway protocol (BGP) and internet protocol (IP) addresses direct those data packets to and from those devices. Multiple hardware and software elements work together every day to connect us to the internet and get data to our devices.
