This means that 2 24 (= 16.777.216) unique OUAs can be assigned per OUI.

Since MAC addresses are assigned directly by the hardware manufacturer, they are also referred to as hardware addresses. The physical address is used to identify a device in computer networks. It is determined and configured by the Institute of Electrical and Electronic Engineering (the last 24 bits) and the manufacturer (first 24 bits) using the. The MAC address (short for media access control address) is the worldwide unique hardware address of a single network adapter.

It is also known as a physical address, and it is also unique for each device.

It is a 48-bit identifier (6 blocks of two hexadecimal characters (8 bits)) that uniquely corresponds to a card or network device. Learn all about the MAC address, how to find it on Windows 10 and explore the various ways to change the MAC address in Windows 10.Learn all about the MAC address, how to find it on Windows 10 and. The MAC address comes from the acronym for Media Access Control.

Bit 25-48 (network adapter identifier): Bits 25 to 48 provide device manufacturers with 24 bits for assigning a unique hardware identifier (organizationally unique address, OUA). What is the MAC address and what can it do for us.

A corresponding service is available, for example, on. The assignment of OUIs is usually public and can be determined via databases.

Bit 3–24 (manufacturer identification): Bits 3 to 24 encode an identifier (organizationally unique identifier, OUI), which is assigned exclusively to hardware manufacturers by IEEE.

Addresses that are only locally unique are called locally administered address (LAA) and are marked with U/L = 1. If U/L = 0, the address is valid worldwide as a universally administered address (UAA).

Bit 2 (registry): The second bit of the MAC address indicates whether it is an address with global validity (universal) or whether the address has been assigned locally (local).

Multicast addresses are identified by I/G = 1 and are addressed to several receivers. If I/G = 0, it is a unicast address for a single network adapter.

This bit is called I/G (short for individual/group). Bit 1 (receiver): The first bit of the MAC address specifies whether it is an individual or group address.The bit sequence of each MAC address is divided into 4 areas, each of which encodes different information.
