The first field is the destination, which can be a specific host, a subnet, the loopback, or a default
route (anything else).
? The second field is the gateway to forward packets intended for the destination.
? The third field is the netmask for the corresponding destination, with 255.255.255.255 for a host
and 0.0.0.0 for a default route.
? The fourth field is the flags (U = route is up; G = use gateway).
? The fifth field is the Maximum Segment Size (bytes) for TCP packets.
? The sixth field is the Windows size for TCP connections over this route.
? The seventh field is the initial route trip time for TCP connections over this route.
? The eighth field is the interface in which this route is connected to.
