Why each option
The dig command is a DNS lookup utility that allows administrators to query name servers and verify that a hostname resolves to the correct IP address.
net view is a Windows command that lists shared resources on a network, not a DNS query tool.
ipconfig displays and manages the local machine's IP configuration but does not perform DNS lookups or resolve hostnames to IP addresses.
The dig (Domain Information Groper) command sends DNS queries to name servers and displays the full resolution response, including the resolved IP address, TTL, and responding server. It is the standard cross-platform tool for troubleshooting DNS name resolution issues and directly tests whether a site resolves correctly.
ifconfig is a Unix/Linux command for configuring network interfaces and does not perform DNS name resolution queries.
