In a Network Programming and Administration Lab, finding the host or domain name along with the corresponding IP address is a fundamental task that helps understand network communication and resource identification. The host name is a human-readable label assigned to a device on a network, while the IP address is a numeric identifier that allows devices to locate and communicate with each other over a network. The process of finding these details can be accomplished using several commands and programming approaches, both in command-line environments and through network programming APIs. On a command-line interface, the most common method to resolve a host name to an IP address is the `ping` command. For example, executing `ping www.example.com` sends ICMP echo requests to the server and shows the IP address in the response. Similarly, the `nslookup` command provides detailed information about a domain, including its IP address, canonical name, and DNS server details. For instance, `nslookup www.example.com` queries the DNS server and returns the corresponding IP address. The `host` command in Linux also serves a
