What is the first 24 bits in a MAC address called?
Historically, MAC addresses are 48 bits long. They have two halves: the first 24 bits form the Organizationally Unique Identifier (OUI) and the last 24 bits form a serial number (formally called an extension identifier).
What are the first three sections of a MAC address called?
The first three pairs of digits in the MAC address are called the OUI (Organizational Unique Identifier), which identifies the company that manufactured or sold the device. For example, a MAC address that begins with 00:1F:33 denotes a Netgear product.
What does the first half of the MAC address indicate?
The First 6-digits (say 00:40:96) of MAC Address identifies the manufacturer, called OUI (Organizational Unique Identifier).
What is the 48-bit MAC address of your computer?
A MAC address also known as a media access control address is a unique 48 bit number identifier assigned to network interfaces. Every piece of hardware with a ethernet, bluetooth or wireless interface has this unique 48 bit number to identify it.
What is Unicast MAC address?
A unicast MAC address is a unique address that is used when a frame is sent from a single transmitting device to a single destination device. In Figure 7-11, the destination MAC address and the destination IP address are both unicast.
What are the sections of a MAC address called?
A MAC address consists of two parts. The Block ID is the first six characters of a MAC address. The Device ID is the remaining six characters. The Block ID is unique to the manufacturer.
What is the length of the MAC address 8 bits 16 bits 32 bits 48 bits?
MAC addresses are 6-byte (48-bits) in length, and are written in MM:MM:MM:SS:SS:SS format.
How many MAC addresses are there?
281 trillion
This 48-bit address space contains potentially 248 (over 281 trillion) possible MAC addresses. The IEEE manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers.
How is a MAC address format?
MAC addresses follow the format, XX:XX:XX:XX:XX:XX, but will sometimes display as XX-XX-XX-XX-XX-XX or XXXXXXXXXXXX. Instructions for finding the wireless MAC address for some commonly used streaming and entertainment devices are shown below.

Multicast MAC address 0180. C200. 0000 is used by 802.1D STP to send native VLAN BPDUs.
What is the first part of a MAC address?
The Block ID is the first six characters of a MAC address. The Device ID is the remaining six characters. The Block ID is unique to the manufacturer.
What is the size of MAC address * 1 point 16 bits 32 bits 48 bits 64 bits?
Explanation: The Ethernet frame has a header that contains the source and destination MAC address. Each MAC address is of 48 bits. 2.
What are the 3 types of MAC address?
There are three types of MAC addresses: Unicast, Multicast, and Broadcast. The way to identify which address type you are viewing is simply look at the first byte. A unicast address’s first byte will be even, like 02, 04, 06, etc. The first byte of a multicast address is odd, such as 01, 03, 05, etc.
Why is it called a MAC address?
Just like each house has it’s own postal address, every device connected on a network has a Media Access Control (MAC) address, that uniquely identifies it.
What is the length of the MAC address 8 bits 16 bits 32 bits?
Answer. MAC addresses are 6-byte (48-bits) in length, and are written in MM:MM:MM:SS:SS:SS format. The first 3-bytes are ID number of the manufacturer, which is assigned by an Internet standards body.
