Static route

Extracted from the Wikipedia article Static routing.
The most prominent example of a static route is a default route, which is often used on devices with a statically configured IP address to provide the device with access to the rest of the network or the internet by default. In contrast to a so-called connected route, which is automatically generated upon address assignment based on the used subnet mask, a static route must be manually configured. Due to this, the configuration may fail if there is no route to the provided gateway at the time of configuration, other than the connected route, which will always succeed, as it does not require a gateway. The gateway of a static route need not be an address, but can also specify an interface in most implementations.
