MAC Address Information

Medium Access Control (MAC) address information search.

Use !mac to analyze MAC addresses and find information about the IEEE Organizationally Unique Identifiers (OUI) used in the creation of 802-defined MAC addresses.

You can analyze 48bit MAC addresses, 64bit MAC addresses, and MAC address prefixes that are 24 bits long or longer.

You can find information for EUI-48 MAC addresses, EUI-64 MAC addresses, and MAC addresses that are not unique with prefixes registered in the Company-ID IEEE registry.

Ethernet interfaces, 802.11 wireless network interfaces (WiFi),Bluetooth interfaces , ATM interfaces, IEEE 802.5 token ring interfaces ,and FDDI interfaces are some of the devices that are using EUI-48 MAC addresses.

EUI-64 addresses are used among others in Firewire interfaces, IPv6 automatic interface addressing, and IEEE 802.15.4 (Zingbee addressing).
