Which Command Is Used to Manually Query a DNS Server to Resolve a Specific Host Name?
When it comes to resolving a specific host name using a DNS server, the command that you can use is called “nslookup.” Nslookup is a powerful tool that helps you troubleshoot and diagnose DNS-related issues. It allows you to manually query a DNS server to obtain information about a specific domain or host name.
To use nslookup, follow these steps:
1. Open the command prompt or terminal on your computer.
2. Type “nslookup” followed by a space.
3. Enter the host name or domain name that you want to resolve.

If the DNS server is able to resolve the host name, nslookup will display the corresponding IP address. Additionally, it provides other useful information such as the DNS server’s name, address, and response time.
