1. Can you explain the significance of the default entry in the routing table, particularly in CIDR notation, and why it is crucial for internet communication?
The default entry in the routing table is extremely significant as if no rule matches the address, the default would definitely match. In CIDR notation default is 0.0.0.0/0 in case of IPv4. The address is configured as an intermediary in the default route. It is crucial because when no other rules match, the default gateway is the one where you send the messages.
The default entry in the routing table plays a crucial role in directing network traffic when no specific route matches the destination address. In CIDR notation, the default entry for IPv4 is represented as 0.0.0.0/0. Essentially, if no other rules in the routing table match the destination IP address, the default route is used. This default route ensures that any packet not matching a more specific route is forwarded to the default gateway. Essentially, the default entry acts as the final pathway, guaranteeing seamless communication in situations where no other routing rules are applicable.
