Explanation

NSLOOKUP (Name Server Lookup) is a command-line tool used to query DNS servers. When given an IP address, it performs a reverse DNS lookup to return the associated hostname - exactly what the technician needs. For example, 'nslookup 192.168.1.10' will return the hostname mapped to that IP in DNS. IPCONFIG displays the local machine's network configuration and does not resolve remote IPs to hostnames. PING can sometimes return a hostname via reverse lookup, but it is not the dedicated tool for this purpose and may not resolve it. NETSTAT shows active network connections and listening ports, not hostname resolution.
