Why each option
This question asks for the command-line tool used to resolve a website's hostname to its corresponding IP address for network configuration verification.
nslookup is a command-line tool used to query the Domain Name System (DNS) to obtain domain name to IP address mappings or other DNS records. An administrator would use nslookup to resolve a website's hostname to its IP address, which is crucial for verifying firewall content filter rules based on IP ranges.
tracert (Windows) or traceroute (Linux/Unix) maps the network path that packets take to reach a destination, showing intermediate router IP addresses, rather than just resolving the destination website's IP address directly.
