You can delete the routes if you no longer want them in your routing table. In the output, you will see a list of network destinations and gateways.

How to change route table in Ubuntu?

Router tables give you a secure, flat work surface to control the material you're machining. This way you can cut joinery, slots, and rabbets very easily. Using a router table also increases shop safety when working with larger materials that would be clumsy or dangerous to set up and rout by hand.

Why do we need route tables?

The main purpose of a routing table is to help routers make effective routing decisions. Whenever a packet is sent through a router to be forwarded to a host on another network, the router consults the routing table to find the IP address of the destination device and the best path to reach it.

What is Route table used for?

A route table contains a set of rules, called routes, that determine where network traffic from your subnet or gateway is directed.

What is route table in Linux?

Where is a route stored?

A routing table is a table or database that stores the location of routers based on their IP addresses. This table acts as an address map to various networks, and is usually stored in the RAM of most routers or forwarding devices.

A hop that outputs * * * means that the router at that hop doesn't respond to the type of packet you were using for the traceroute (by default it's UDP on Unix-like and ICMP on Windows).
