Explanation
tracert (traceroute) reveals the IP address of every hop along the path to a destination, making it the right tool when the next-hop router's IP is unknown - it actively probes and displays each intermediate router's address in sequence. ping only confirms reachability to a known address and returns no routing path information. nslookup resolves domain names to IP addresses via DNS, which is irrelevant when you're investigating router hops at Layer 3. nmap is a port/service scanner used for network enumeration, not for tracing routing paths.
Memory tip: Think of tracert as "tracing the route" - the name literally contains trace + rt (route). If you need to discover unknown hops, you need something that traces the route.
