MAC ADDRESS FLOODING DEFINITION SERIES
MAC ADDRESS FLOODING DEFINITION MAC

The first three octets (in transmission order) identify the organization that issued the identifier and are known as the Organizationally Unique Identifier (OUI). A universally administered address is uniquely assigned to a device by its manufacturer these are sometimes called burned-in addresses. Addresses can either be universally administered addresses or locally administered addresses.

This 48-bit address space contains potentially 2 48 or 281,474,976,710,656 possible MAC addresses.ДЄll three numbering systems use the same format and differ only in the length of the identifier. The original IEEE 802 MAC address comes from the original Xerox Ethernet addressing scheme. The IEEE claims trademarks on the names EUI-48 and EUI-64, in which EUI is an acronym for Extended Unique Identifier. MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64. A network node may have multiple NICs and will then have one unique MAC address per NIC. It may also be known as an Ethernet hardware address ( EHA), hardware address or physical address. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model. MAC addresses are used for numerous network technologies and most IEEE 802 network technologies, including Ethernet. For other similar terms, see Mac.ДЄ Media Access Control address ( MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment.
