MAC ADDRESS WIRESHARK MAC

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

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).

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). To show the MAC address column in Wireshark, you can go to Edit -> Preferences, select the Columns tab, and then for the Source and Destination columns.Alternatively you can use the Preferences dialog to configure your columns, but it is. That way you'll get a new column containing the MAC address, which will be exported in the. Multicast addresses are identified by I/G = 1 and are addressed to several receivers. You can add a column containing the MAC address you want by selecting it in the decode pane and using the popup menu to 'Apply as Column'. 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.
