Display network routes on Linux

With netstat

Run netstat -r or netstat --route. Add -n or --numeric for numeric output. Example from a laptop, on which all traffic is routed out the wireless interface:

[email protected] ~ $ netstat -rvn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
0.0.0.0         192.168.88.1    0.0.0.0         UG        0 0          0 wlan0
169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 wlan0
192.168.88.0    0.0.0.0         255.255.255.0   U         0 0          0 wlan0

With route

Run route with optional -n for numeric output. The result is almost identical to that of netstat. Example from the same machine as above:

[email protected] ~ $ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.88.1    0.0.0.0         UG    0      0        0 wlan0
169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 wlan0
192.168.88.0    0.0.0.0         255.255.255.0   U     9      0        0 wlan0

With ip

Run ip route. Example from the same machine as above:

[email protected] ~ $ ip route
default via 192.168.88.1 dev wlan0  proto static 
169.254.0.0/16 dev wlan0  scope link  metric 1000 
192.168.88.0/24 dev wlan0  proto kernel  scope link  src 192.168.88.253  metric 9
