Can we communicate through MAC address?

1 Answer. You are correct. ARP does communicate on the same subnet using MAC addresses. Your answer could be improved to include that the computers have to be on the same subnet.

What is a MAC address used to communicate with?

Ethernet
A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

How do devices find MAC addresses?

From the main menu, select Settings. Select System Settings. Select System Information. The MAC Address will then be displayed on the screen.

What does MAC device mean?

Starting in Android 8.0, Android devices use randomized MAC addresses when probing for new networks while not currently associated with a network. In Android 9, you can enable a developer option (it’s disabled by default) to cause the device to use a randomized MAC address when connecting to a Wi-Fi network.

How can you tell if someone is connected to your WIFI?

Look for a link or button named something like “attached devices,” “connected devices,” or “DHCP clients.” You may find this on the Wi-Fi configuration page, or you may find it on some sort of status page. On some routers, the list of connected devices may be printed on a main status page to save you some clicks.

Why would you need to know the MAC address of a device?

What is MAC address and why is it used?

MAC addresses are used in LANs for communication between devices on the same network segment. Devices that want to communicate need to know the MAC address of other device before sending out packets. Switches also use MAC addresses to make accurate forwarding and filtering decision.

What is the broadcast MAC address of a device?

Broadcast MAC address Broadcast MAC address represents all devices in the network. The IEEE has reserved the address FFFF.FFFF.FFFF as the broadcast MAC address. Any device that wants to send the data to all devices of the network, can use this address as the destination MAC address.
