What destination MAC address would be included in a frame sent from a source device to a destination device on the same local network?
The destination MAC address in a frame sent from a source device to a destination device on the same local network would be the MAC address of the destination device.
MAC addresses are unique identifiers assigned to network interface cards (NICs) of devices. When a device wants to send data to another device on the same network, it needs to know the MAC address of the destination device.
To determine the MAC address of the destination device, the source device uses Address Resolution Protocol (ARP) to send an ARP request broadcast on the local network. The ARP request asks “Who has the IP address X?” The device with the matching IP address will respond with its MAC address.
Once the source device receives the MAC address of the destination device from the ARP response, it can insert the destination MAC address into the frame header before sending it over the network.
It is important to note that the destination MAC address is specific to the local network and will be different when communicating with devices outside of the local network (e.g., devices on different subnets or on the internet). In those cases, the destination MAC address will be the MAC address of the default gateway or router.
