Any traffic destined for the network address 220.127.116.11 (the local network) does not need a gateway, and should be sent out interface eth0.
Any traffic intended for network address 127.0.0.1 (the loopback address) should be sent out the loopback interface.
Traffic not intended for the local network or the loopback address defaults to the machine 18.104.22.168, which is the gateway machine.
U indicates that the route is UP.
G indicated that the route is a gateway.
Reading Routes and IP Information
Assuming an already configured machine named tristan, let uslook at the IP addressing and routing table.
Next we will examine how the machine communicates with computers (hosts) on the locally reachable network.
We will then send packets through our default gateway to other networks. After learning what a default route is, we will look at a static route.
One of the first things to learn about a machine attached to an IP network is its IP address. We will begin by looking at a machine named tristan on the main desktop network (192.168.99.0/24).
The machine tristan is alive on IP 192.168.99.35 and has been properly configured by the system administrator. By examining the route and ifconfig output we can learn a good deal about the network to which tristan is connected.
