Unveiling Hostnames using `dnslookup`

The `dnslookup` command provides a powerful tool for resolving hostnames to their corresponding IP addresses. This utility leverages the Domain Name System (DNS) to translate human-readable hostnames into numerical IP addresses that computers understand. To utilize this feature, simply run the `dnslookup` command followed by the hostname you wish to find. For instance, typing `dnslookup google.com` would display the IP address associated with the Google domain.
