Which type of static route creates a gateway of last resort?

A default static route is a type of static route that creates a gateway of last resort. It is used to route traffic to any destination that is not in the routing table, and is typically used when a router has only one path to the outside network. The default static route is also known as the 0.0.0.0/0 route, which means that it matches any destination address (0.0.0.0) with any subnet mask (/0). When a packet is received by the router that does not match any other route in the routing table, the router will forward the packet to the next hop specified in the default route. This is useful for routers that do not have specific knowledge of all the networks they might encounter, such as border routers or routers that connect to the internet.
