The ROUTING TABLE is a table maintained in the kernel that determines how packets are routed to other systems. A number of programs may add or delete routes from the routing tables, including route, ifconfig, in.routed and in.rdisc. The routing table consists of three types of routes: HOST ROUTES are checked first and define a route to just one host. NETWORK ROUTES are checked second and define a route to all the hosts on one network. DEFAULT ROUTES are used as a catch-all, when no host or network routes are found to a destination. They usually send to a more knowledgeable routing machine, which has a better chance of being able to find a host or network route to the destination.
