Which utilities can be used for validating domain name-to-IP address mappings?

RDP
dig
SSH
nslookup

The correct answer is: dig

The correct choice for validating domain name-to-IP address mappings is "dig." This command-line utility is specifically designed to query DNS (Domain Name System) servers and retrieve information about domain names, including their associated IP addresses. When you use dig, it allows you to perform detailed DNS lookups and can provide you with various types of data, making it a highly valuable tool in network administration and troubleshooting. Both "dig" and "nslookup" serve similar purposes in terms of querying DNS records; however, dig is often preferred among advanced users for its performance and the detailed information it provides, such as response time and server queried. Using dig, one can perform a query by simply typing `dig example.com`, which will return the IP address associated with that domain name, among other relevant DNS information. RDP (Remote Desktop Protocol) and SSH (Secure Shell) are protocols primarily used for remote connections to machines, rather than for querying DNS information. Therefore, they are not suitable for this particular task of validating domain name-to-IP address mappings.
