traceroute

Good afternoon

Can anyone explain traceroutes to me and when it would be necessary/what situations would call one to use it?

Traceroute checks the path of network packets from you to somewhere else by sending packets with increasingly larger time-to-live(TTL) values. A TTL of one will only let a packet jump one host before it gives up and returns an error message instead.

So by sending packets to your destination with TTL's of 1, then 2, then 3, and so on you get replies from hosts 1, 2, 3, etc. along your network path, letting you see the precise path you're taking provided these hosts send proper ICMP error replies back.
