Router uses IP address of destination node to do the direct packet switching..while bridge & switch uses the MAC address to packet forwarding.

The router will use gateway of last resort IP address to forward packets destined to 192.168.254.254.
You would only need a default gateway address if you wanted to route packets outside your local area network.
NAT (Network Address Translation) A service that translates a private IP address to a public IP address in packets destined for the internet, then translates the public IP address in the reply to the private address.
No, it is not. A destination IP address may be any address, usually on a completely different network. The default gateway address is used to determine where to send packets that need to be routed outside of the current local area network.
A public address is one that is seen on the Internet and can be routed. A private IP address is only visible within its organization network and any packets containing a destination address using a private address will not be routed outside the organization.
The localhost address is designed to verify that the software for networking has been installed and is operating correctly. It does not pass any packets to the network.
The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world. If the default gateway is not configured correctly, the usual symptoms are that your computer can connect within the local network, but it can't connect to the outside.You have to obtain the address which you should assign as the default gateway from your network administrator, or from your ISP.The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world.

1. Filter packets leaving your network with source addresses that do not originate inside your network. 2. Filter packets entering your network with a broadcast address for a destination
Using spoofing, an intruder can fake the source address of his packets and make them look like they originated on the trusted hosts.The basic idea of anti-spoofing protection is to create a firewall rule assigned to the external interface of the firewall that examines source address of all packets crossing that interface coming from outside. If the address belongs to the internal network or the firewall itself, the packet is dropped.
routers work at layer 3 (network) which usually means TCP/IP. Routing decisions are made based on a packets DESTINATION IP address.
In a packet-switched data network, what is used to reassemble the packets in the correct order at the destination device?
