Source and Destination IP Addresses in Network Communication

Explanation:

Source and Destination IP Addresses for Packet Transmission

When Router R1 needs to send a packet to all stations on the network, it will use its own IP address as the source and the broadcast IP address of the network as the destination.

Source IP: Router R1 IP address

Destination IP: Broadcast IP address of the network

In technical terms, the broadcast address for an IPv4 network is typically the last address in the IP range of the network, which has a host portion of all binary ones. For example, if the network is 192.168.1.0/24, the broadcast address would be 192.168.1.255.

By using the router's own IP address as the source and the broadcast IP address as the destination, the router can effectively send the packet to all stations on the local network. This method ensures that the packet reaches every device connected to the network, allowing for efficient communication across all stations.
