How to see the routing table on Mac OSX

Do you have a Macbook Pro or Macbook Air and want to know how to show the routes it has in the routing table? Are you looking for the Windows command route print equivalent in OSX? This post is for you.

Show Routes

This is the command to show routes on a Mac OSX:

netstat -rn

The -r flag means to show routes.

The -n flag means to not resolve IPs to hostnames.

Here is an example output of the command:

$ netstat -rn

Internet:
Destination        Gateway            Flags        Refs      Use   Netif Expire
default            192.168.20.1       UGSc           39        0     en0
127.0.0.1          127.0.0.1          UH              3    11132     lo0
192.168.20/24      link#4             UCS             8        0     en0
192.168.20.1       0:1f:ca:88:96:8c   UHLWIir        40       22     en0   1025
192.168.20.255     ff:ff:ff:ff:ff:ff  UHLWbI          0        8     en0

In the case above, the default gateway of this Mac is 192.168.20.1. Meaning all routes are pointing to that system.
