Curl is a tool used to transfer data from or to a server using various protocols, including HTTP and FTP. While it can be used to fetch web pages, it does not specifically look up DNS records, thus it is not the correct answer.

C) dig

Dig is specifically designed to query DNS name servers for information about host addresses, mail exchanges, name servers, and related data. It provides detailed output and is the standard tool for DNS lookups, making it the correct choice.

D) ip

The ip command is used for network interface configuration and management tasks, such as viewing or manipulating routing tables and network interfaces. It does not serve the purpose of querying DNS records, rendering it an incorrect option.

Conclusion

All other options either serve different functions or lack the capability to perform DNS queries, confirming that they are not suitable choices for this question.
