Linux comes with two utilities/sbin/route/sbin/ip routeWhat is the difference between the two and what is the rule of thumb to use when you decide which one of the two you should use? I know they're both documented in two separate locations,man 8 routeman 8 ip-route
What is the difference between `/sbin/ip route` and `/sbin/route`?

route is the old traditional tool and available on numerous Unix systems. ip belongs to the iproute2 suite which is a Linux only tool and uses the Netlink API, which is a socket like interface for accessing kernel information about interfaces, address assignments and routes. It replaces most of the functionality of ifconfig, route, netstat and a few others.I assume you're on Linux, then you should use ip since route and ifconfig are deprecated, although still widely used.Further reading:  ifconfig vs iproute2iproute2: Life after ifconfigDeprecated Linux networking commands and theirreplacements
