In 802 networks, the of the is divided into two sub-layers: the and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the address.
How to Find a MAC Address To display your MAC address on a Windows NT/2000/2003/XP/Visa computer.

Label of a UMTS router with MAC addresses for LAN and WLAN modules A media access control address ( MAC address) of a device is a assigned to a (NIC) for communications at the of a network segment. MAC addresses are used as a for most network technologies, including,. In this context, MAC addresses are used in the protocol sublayer. A MAC may be referred to as the burned-in address ( BIA). It may also be known as an Ethernet hardware address ( EHA), hardware address or physical address (not to be confused with a ). A may have multiple NICs and each NIC must have a unique MAC address.
A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. Internet explorer 6 for mac. MAC addresses are used for numerous network technologies and most IEEE 802 network technologies including Ethernet. MAC does indeed have a meaning. MAC, in fact, is an acronym. What does MAC stand for? MAC started out as a two-person startup created by makeup artist and photographer Frank Toskan and salon.
Sophisticated such as a or may require one or more permanently assigned MAC addresses. MAC addresses are most often assigned by the manufacturer of a NIC and are stored in its hardware, such as the card's or some other mechanism.
What Does A Mac Address Do
A MAC address may include the manufacturer's (OUI). MAC addresses are formed according to the rules of one of three numbering name spaces managed by the (IEEE): EUI-48 (it replaces the obsolete term MAC-48) and EUI-64. EUI is an abbreviation for Extended Unique Identifier. Diagram showing the structure of a MAC-48 network address, explicitly showing the positions of the multicast/unicast bit and the OUI/local address type bit. The original MAC address comes from the original Ethernet addressing scheme. This address space contains potentially 2 48 or 281,474,976,710,656 possible MAC addresses.
The manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers. The IEEE has a target lifetime of 100 years (until 2080) for applications using EUI-48 space and restricts applications accordingly. The IEEE encourages adoption of the more plentiful EUI-64 for non-Ethernet applications. The distinction between EUI-48 and MAC-48 identifiers is purely nominal: MAC-48 was used to address hardware interfaces within existing 802-based networking applications; EUI-48 is also used to identify other devices and software, for example. The IEEE now considers the label MAC-48 to be an obsolete term. EUI-48 should be used for this purpose. Office 2013 for mac free download. In addition, the EUI-64 numbering system encompasses both MAC-48 and EUI-48 identifiers by a simple translation mechanism, but now it is deprecated.
To convert a MAC-48 into an EUI-64, copy the, append the two FF-FF (though now as MAC-48 is deprecated, FF-FF will never be used) and then copy the organization-specified extension identifier. To convert an EUI-48 into an EUI-64, the same process is used, but the sequence inserted is FF-FE. In both cases, the process can be trivially reversed when necessary. Organizations issuing EUI-64s are cautioned against issuing identifiers that could be confused with these forms. — one of the most prominent standards that uses a Modified EUI-64 — treats MAC-48 as EUI-48 instead (as it is chosen from the same address pool) and toggles the U/L bit (as this makes it easier to type locally assigned IPv6 addresses based on the Modified EUI-64).

This results in extending MAC addresses (such as IEEE 802 MAC address) to Modified EUI-64 using only FF-FE (and never FF-FF) and with the U/L bit inverted. An is an inactive registry activity which has been replaced by the MA-S (MA-S was previously named ) registry product as of January 1, 2014. The IAB uses a OUI from MA-L (MA-L registry was previously named OUI registry, the term OUI is still in use, but not for calling a registry ) belonging to the IEEE Registration Authority, concatenated with 12 additional IEEE-provided bits (for a total of 36 bits), leaving only 12 bits for the IAB owner to assign to their (up to 4096) individual devices. An IAB is ideal for organizations requiring not more than 4096 unique 48-bit numbers (EUI-48).
