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. When data packets from the internet hit your router, that router needs to be able to send them to the right device on its network. RELATED: What Is a Network Adapter? How Does a MAC Address Work?

ETHERNET ADAPTER MAC ADDRESS CODE

Large network adapter manufacturers like Dell and Cisco will often code their identifiers, called their Organizationally Unique Identifier (OUI), into the MAC addresses of devices they make. MAC addresses are always a 12 digit hexadecimal number, with the numbers separated every two digits by a colon or hyphen. 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.
