Which command will allow you to determine the IP address of www.widgets.com?

traceroute www.widgets.com
nslookup www.widgets.com
get www.widgets.com
dig www.widgets.com

The correct answer is: nslookup www.widgets.com

To determine the IP address of a domain name such as www.widgets.com, the nslookup command is particularly useful. This command queries the Domain Name System (DNS) to obtain the mapping of the domain name to its corresponding IP address. nslookup can return both the IPv4 and IPv6 addresses, depending on the configuration and the DNS records existing for that domain. Using nslookup, you can interactively or non-interactively query DNS records, making it an efficient tool for network diagnostics and troubleshooting. It also provides additional information, such as the authoritative nameservers for a domain if needed. While the other options provide useful networking information, they do not focus specifically on resolving a domain name to an IP address in the same straightforward manner as nslookup. Traceroute, for instance, is a tool used to trace the path packets take to reach a destination and does not return the IP address directly. The get command is not standard for querying DNS records, and dig, while capable of performing the same function as nslookup, is often less common in environments where nslookup is typically used for quick lookups. Thus, nslookup stands out as the most relevant answer for this particular question.
