Handling IP Datagrams

The internet sends an IP datagram across a single network by placing it inside a network packet, making it appear as simply data.

When the network packet arrives at the next computer, the computer ``opens'' the packet and extracts the datagram to determine how to process it.

When a router determines that the datagram must be sent across another network, the router creates a new network packet.
