In computer networking a routing table, or routing information base (RIB), is a data table stored in a router or a networked computer that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes.
If you specify the address of one of your local interfaces, it will be used to decide about the interface to which the packets should be routed to. You can manually add / modify / edit routing table using route and ip command.

These associations tell a router that a particular destination can be optimally reached by sending the packet to a specific router that represents the "next hop" on the way to the final destination.

If the node cannot directly connect to the destination node, it has to send it via other nodes along a proper route to the destination node.
Most nodes do not try to figure out which route(s) might work; instead, a node will send an IP packet to a gateway in the LAN, which then decides how to route the "package" of data to the correct destination.
The next hop association can also be the outgoing or exit interface to the final destination.
