Route table lookup
subnet mask destination IP address
destination host address
The node sends out an ARP request with the destination IP address.
The destination host 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.
In a datagram network, the destination addresses are unique. They cannot be duplicated in the routing table.

IP source and destination address
Generally speaking, routers will unicast-forward incoming packets which have a network broadcast address as destination, unless they are directly connected to that network/subnet and therefore know that the destination address is a broadcast address
the network portion of the destination ip address
In a packet-switched data network, what is used to reassemble the packets in the correct order at the destination device?
It uses the MAC address, Media Access Control. Every packet sent from a computer contains its MAC address. The router stores this in its routing table. When it receives a packet with a destiation address of that MAC address, then it forwards it to that computer. This is called NAT, Network Address Translation. It uses the Destination IP address
