What does traceroute reveal about network paths?
- A.Traceroute only shows the destination
- B.Traceroute scans for vulnerabilities
- C.Traceroute shows every router (hop) between your computer and the destination, along with the time taken at each hop - this reveals the network path, identifies where delays or packet loss occur, and can expose network infrastructure and ISP relationships
- D.Traceroute only works on local networks
Why C is correct
Traceroute: sends packets with incrementing TTL (1, 2, 3...), each router decrements TTL and replies with ICMP Time Exceeded when TTL=0. Shows: each hop IP, round-trip time, and path to destination. Security use: map network topology, identify filtering points, and detect routing anomalies.
