To trace the route of an IP packet from your system to a destination, you can use the traceroute command in a Bash shell. Traceroute works by sending a series of packets with gradually increasing time-to-live (TTL) values, starting at 1 and ending at a specified maximum value. The TTL value determines how many hops a packet can take before it is discarded.
To use traceroute, you need to specify the destination IP address or hostname as an argument. For example, to trace the route to Google's servers, you can use the following command:
traceroute google.com
This will send a series of packets with increasing TTL values to the destination, and display the IP addresses and hostnames of the intermediate routers that the packets pass through. Traceroute can be used to diagnose connectivity issues and to understand the path that packets take through the network.
It's worth noting that some systems may have a utility called tracepath instead of traceroute, which performs a similar function but uses a different algorithm. You can use tracepath in the same way as traceroute.
