The route is nothing but a path or way to the specific or range of destination IP addresses. Linux kernel maintains these routes called as kernel routing table and will route the traffic accordingly.
You can use any one of them to display the routing table
The command route is used to modify and check the existing routes. To check the routing table using route command,
This will display the list of routes currently configured
Command: route -n
$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0 192.168.0.0 0.0.0.0 255.255.255.0 U 9 0 0 wlan0
This will give the output with out resolving the names
This command gives the statistics about the network. With this command you can do more than just printing routing table,
Print network connections,
masquerade connections, and
To check the routing table,
Command: nestat -rn
$ netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
Option -r is to display the routing table
Option -n is not to resolve the names. Print the IP addresses only
To check routing table using command ip
Command: ip route list
$ ip route list default via 192.168.0.1 dev wlan0 proto static 192.168.0.0/24 dev wlan0 proto kernel scope link src 192.168.0.5 metric 9
To find hops, route of the destination and how your machine is reaching the destination you use tracepath
Where you can replace howto.lintel.in with specific domain or IP address.
