The IP address 255.255.255.255 is reserved for local broadcast.
It will send the frame to all hosts except host A.This is a MAC broadcast address. All hosts on that subnet will receive the packet or frame. With the exception of the sending host of course.
The MAC address is a unique identifier for a networking card. Each networking card has a MAC address assigned to it during it's manufacturing, and thus it does not change when a computer moves between networks (unlike an IP address which is assigned by the network). A few things to note: - A computer only has a MAC address if it has a physical or virtual network card - A computer has as many MAC addresses as it has networking cards - MAC addresses CAN be modified before being broadcast to the rest of the network, however generally this results in the computer not receiving intended traffic and requires specialized software
It is a broadcast address
the Ip address is used to broadcast messages, such as the Emergency Broadcast message recived on your television
It duplicates the frame to all Ethernet ports, except the port it came from. A switch's MAC table is built not from destination addresses it receives, but by the source MAC addresses. So the frame is broadcast throughout the broadcast domain, until the end device with a matching MAC address responds to the broadcast, thus giving the switch a new source address to add to its MAC table.
ARP (address resolution protocol) is used in this case. Basically, one computer asks, for example, "who has IP address 10.0.0.15" (the message is sent as a broadcast), and the computer with this IP address replies, including its MAC address.ARP (address resolution protocol) is used in this case.

It will broadcast to every port in the vlan.
It will not forward the frame to another network
Yes, broadcasts can occur at the Layer 2 level in a network using Ethernet. The MAC address used for broadcast is FF:FF:FF:FF:FF:FF, which signifies that the frame should be sent to all devices on the local network segment. When a device sends a frame with this MAC address, all devices within the same broadcast domain will receive and process the frame.
A switch would record multiple entries for a single switch port in its MAC address table if it does not contain the Mac address of a particular destination in the address table. It will broadcast to all ports besides the port where entry comes from.
FF-FF-FF-FF-FF-FF
A switch floods a frame when it doesn't have the destination MAC address in its MAC address table. The frame is then forwarded out of all interfaces except the one it was received on in an attempt to find the correct host.
When a packet arrives at the network layer on the sender's device, it is encapsulated into a frame whose destination MAC address is all fs (FF-FF-FF...). The switch connected to the sender's device recognizes the all fs MAC address as a broadcast message and hence forwards it to all its ports.
In a Reverse Address Resolution Protocol (RARP) request, the destination MAC address is typically set to the broadcast address (FF:FF:FF:FF:FF:FF). This allows the RARP request to be sent to all devices on the local network segment, ensuring that the RARP server, which is responsible for resolving the MAC address to an IP address, can receive the request from any client that needs to determine its IP address.
A host on a network needs to broadcast an ARP request to advertise its Mac address. The networking world is very chatty in nature and when a new network host is available it immediately broadcasts its Mac address as with a ARP message. Also when a particular network host needs to send a data packet to another network host available in the same LAN whose Mac address is unknown, the first network host sends out a ARP message requesting for the destination network hosts MAC address.
A computer uses the Address Resolution Protocol (ARP) to find another machine's MAC address. When it needs to communicate with another device on the same local network, it sends out an ARP request, which is a broadcast message that asks, "Who has this IP address?" The device that owns that IP address responds with its MAC address. Once the requesting computer receives the MAC address, it can then send data directly to the intended device.
