Route Table Viewing

Viewing the route table is done using the 'route' or 'netstat -r' command. An example routing table:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
204.141.72.92   0.0.0.0         255.255.255.252 U     0      0        0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         204.141.72.93   0.0.0.0         UG    0      0        0 eth0

In the above table, we see a route for a LAN via an Ethernet interface, a route for the loopback interface (a virtual interface used to allow applications to connect without ever sending packets across the network) and a default route.
