Discerning the gateway address (deprecated method)

With net-tools installed, we can also use the route command to find our default route out:

$ route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         gateway         0.0.0.0         UG    102    0        0 eth0
10.0.2.0        0.0.0.0         255.255.255.0   U     102    0        0 eth0
192.168.33.0    0.0.0.0         255.255.255.0   U     100    0        0 eth1
