# route
> Manually manipulate the routing tables.
> Necessitates to be root.
- Add a route to a destination through a gateway:
`sudo route add {{dest_ip_address}} {{gateway_address}}`
- Add a route to a /24 subnet through a gateway:
`sudo route add {{subnet_ip_address}}/24 {{gateway_address}}`
- Run in test mode (does not do anything, just print):
`sudo route -t add {{dest_ip_address}}/24 {{gateway_address}}`
- Remove all routes:
`sudo route flush`
- Delete a specific route:
`sudo route delete {{dest_ip_address}}/24`
- Lookup and display the route for a destination (hostname or IP address):
`sudo route get {{destination}}`
