What is the 48 bit Ethernet address MAC address of your computer?
In a LAN, each node is assigned a physical address, also known as a MAC/Ethernet address. This address is unique to each of the nodes on the LAN and is 6 bytes (48 bits) long, which is burned on the Ethernet card (also known as the network interface card). Ethernet is a byte-count protocol.
What does a destination address of FFFF FFFF FFFF mean?
Notice the Layer 2 Destination is ffff. ffff. ffff , this is the special reserved MAC address indicating a broadcast frame. This is what makes an ARP Request a broadcast. Had Host A chosen to send this frame using a specific host’s MAC address in the destination, then the ARP request would have been unicast.
What does FF FF FF FF FF FF mean?
Broadcast MAC Address – ff:ff:ff:ff:ff:ff In other words; “send once receive all”.
Is MAC address the same as Ethernet address?
Each device on a local area network must have a unique MAC address assigned. The MAC address is often referred to as the Ethernet Address on an Ethernet network. They are in fact the same thing. The Ethernet address is 48 bits long and normally displayed as 12 hexadecimal digits.
Why are MAC addresses hardcoded?
Your Mac has a media access control address (confusingly for Mac users, it’s called the MAC address) that uniquely identifies your laptop. This string of letters and numbers is hard-coded into your device in the factory, so it’s impossible to change on a permanent basis.
What is the destination address in the Ethernet frame?
Ethernet frame. The next 6 bytes are the destination address — the MAC address of the intended recipient of the packet. Next is the source address, the MAC address of the sender.
Where in the ARP request does the question appear?
d) Where in the ARP request does the “question” appear – the Ethernet address of the machine whose corresponding IP address is being queried? The field “Target MAC address” is set to 00:00:00:00:00:00 to question the machine whose corresponding IP address (192.168. 1.1) is being queried.
What happens to a frame with destination MAC address FFFF FFFF FFFF?
Once the Ethernet frame reaches the network switch, if the destination MAC address is broadcast MAC address (ff:ff:ff:ff:ff:ff), the network switch will forward the Ethernet frame to all its active ports, so that all the devices in the broadcast domain will receive a copy.
How do I find MAC address on my Network?
You can also find the MAC address by looking at the details of your network adapter in Windows. 1. Search “View network status and tasks” in the taskbar and click on it. (Or navigate to Control Panel > Network and Internet > Network and Sharing Center) 2. Click on your network connection. 3. Click the “Details” button.
What is an example of a MAC address?
The MAC Address is a six-byte number or 12-digit hexadecimal number that is used to uniquely identify a host on a network. An example of a MAC address is 1F-2E-3D-4C-5B-6A and it falls into the Layer 2 networking protocol of the OSI model. In today’s networks, ARP ,…
What is MAC address?
A MAC address is a unique identification number or code used to identify individual devices on the network. Therefore, it’s also sometimes referred to as a hardware or physical address.
What is the size in bits of a MAC address?
The Format of a MAC Address. Traditional MAC addresses are 12-digit (6 bytes or 48 bits) hexadecimal numbers.
