Then, to check a specific domain, enter `set server [DNS server IP]` and press enter. Follow this by typing the domain name you want to test and hit enter. For instance, `google.com`. This process queries the specified DNS server to resolve the domain name, and you should see the domain’s IP addresses as a response if the server is working correctly.
