traceroute:tldr:edc80

The command "traceroute -n ${host}" is used to trace the route that packets take from the local machine to a specified host on a network. Here's a breakdown of the command and its components:

• "traceroute": This is the command itself, used to initiate the traceroute process.
• "-n": This option is used to display IP addresses instead of hostname/domain names in the traceroute output. It avoids performing reverse DNS lookups, which can speed up the process.
• "${host}": This is a placeholder for the desired destination host. You need to replace "${host}" with the actual hostname or IP address of the target you want to trace the route to.

For example, if you want to trace the route to Google's DNS server at 8.8.8.8, you would use the command: traceroute -n 8.8.8.8

The traceroute command sends a series of packets with an increasing Time-To-Live (TTL) value and records the IP addresses of the routers or network devices encountered along the way. By analyzing the traceroute output, you can determine which routers the packets are passing through and potentially identify network issues or bottlenecks.
