+### Get Outside IP
+
+For VPN and other applications using a tunnel it can be useful to check the
+outside IP of your system.
+Together with `awk` only the outside IP address can be displayed.
+This is done with the command `ip route get 1.2.3.4 | awk '{print $7}'`.
+Alternatively it can be done without `awk` by simply running the command
+`ip route get 1.2.3.4` and checking for the seventh column.
