Which command would you use to check DNS resolution of a specific hostname?

The command that is most commonly used to check DNS resolution of a specific hostname is "nslookup." This utility is designed specifically for querying the Domain Name System (DNS) to obtain domain name or IP address mapping information. When you use nslookup, you can perform lookup operations to retrieve the IP address associated with a hostname or vice versa. It provides a simple interface to interact with DNS servers and can also help troubleshoot DNS-related issues.

While "dig" (which stands for Domain Information Groper) is also used for DNS queries and provides detailed information about DNS records, it is often regarded as more advanced and typically favored by network administrators for in-depth DNS analysis. Nevertheless, for straightforward hostname resolution, "nslookup" is widely used due to its simplicity and ease of access.

The "ping" command, on the other hand, primarily checks the reachability of a host and can reveal the IP address associated with that host through DNS resolution indirectly, but it is not a dedicated DNS query tool. "Traceroute" focuses on displaying the route packets take to reach a network destination, which does not specifically address DNS resolution.

In summary, "nslookup" is the appropriate choice for checking DNS resolution as it directly queries DNS servers to resolve hostnames
