To retrieve the IPv4 addresses associated with a specific host name, the nslookup (Name Server Lookup) utility is the most direct and appropriate tool. It is specifically designed to query the Domain Name System (DNS) to obtain domain name or IP address mapping and other DNS records.

• ipconfig is used for viewing and managing local TCP/IP interface configurations.
• tracert is used to determine the path (route) taken to a destination.
• netstat displays active network connections and protocol statistics.

By providing the host name www.companypro.net as the argument to nslookup, the utility queries the configured DNS server and returns the associated A (IPv4) or AAAA (IPv6) records.
