Home routers set up their routing tables automatically when connected to the ISP, a process called dynamic routing. They generate one routing table entry for each of the ISPs DNS servers (primary, secondary and tertiary if available) and one entry for routing among all the home computers. They may also generate a few additional routes for other special cases including multicast and broadcast routes.
Most residential network routers prevent you from manually overriding or changing the routing table. However, business routers typically allow network administrators to manually update or manipulate routing tables. This so-called static routing can be useful when optimizing for network performance and reliability.
