MAC Address Vendor Lookup
It allows MAC addresses to be 48-bits long. So, there are 2 48 (or 281,474,976,710,656) possible MAC addresses. MAC addresses identify many things, such as the type of device being used. A MAC address is mainly used by a switch to direct the data to the right place almost like a home address. The IP is the road name and the MAC address is the How to Change a Computer's Mac Address in Windows (with Jan 06, 2020 MACアドレス - Wikipedia MACアドレス（マック・アドレス、英語: Media Access Control address ）とは、ネットワーク上で、各ノードを識別するために設定されているLANカードなどのネットワーク機器のハードウェアに（原則として）一意に割り当てられる物理アドレスである。 OSI参照モデルでいえば、第2層（データリンク層 IEEE 802.1X - Wikipedia IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.. IEEE 802.1X defines the encapsulation of the Extensible Authentication Protocol (EAP) over IEEE 802, which is known as "EAP over LAN" or EAPOL.

IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
Every network-compatible device can be identified by its MAC (media access control) address, a unique 17-character string of letters, numbers and colons. A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet. All MAC protocol data units contain addressing information. The addressing information consists of two fields: the destination MAC address and the source MAC address. Both of these address fields are 48-bit fields; the structure and semantics of the address field are defined in ISO/IEC 10039.
