Windows Command Prompt vs Windows PowerShell:

Unleashing the Full Potential of DNSSince its introduction in 1981, Windows Command Prompt (CMD) has been the go-to tool for system control and configuration. With a simple black window and a prompt, CMD offers direct control over your system, making it ideal for executing single-line commands. On the other hand, Windows PowerShell, first released in 2006, provides a robust scripting system, administrative capabilities, and the ability to execute batch commands. Its blue window and powerful cmdlets (command-lets) have revolutionized the way administrators interact with the system. Unlike CMD, PowerShell is not limited to console programs and offers cross-platform compatibility with support for Linux and macOS through .Net 5.0. Additionally, PowerShell seamlessly integrates with various libraries across different systems, enhancing its flexibility and efficiency.

Accessing Windows Command Prompt and PowerShell:

Unveiling the GatewaysTo harness the power of Windows Command Prompt, you have multiple options for accessing it. You can simply click on the search icon in your taskbar, type "command prompt" or "cmd," and select the app from the search results. Alternatively, you can use the keyboard shortcut Win + R to open the Run command, type "cmd," and hit enter. Voila! You're now ready to explore the Command Prompt.

For those inclined towards Windows PowerShell, the access methods are identical to those for Command Prompt. Instead of typing "cmd," you enter "PowerShell" in the search or Run Command window. However, there is an additional option for accessing PowerShell as an Administrator by pressing Win + X, which opens a menu with various Windows utilities, including PowerShell.

Note: Windows PowerShell ISE (Integrated Scripting Environment) provides a user-friendly interface compared to the standard PowerShell, resembling Command Prompt in appearance.

Windows Command Prompt Commands for Advanced DNS Management

Now, let's dive into the crux of advanced DNS troubleshooting using Windows Command Prompt. These commands are invaluable for diagnosing and verifying DNS records. Each command plays a specific role in unraveling the mysteries of DNS. Let's explore some of the most useful ones:


The nslookup command is an indispensable tool for diagnosing DNS name resolution issues. It allows you to find the IP address of a host, perform a reverse DNS lookup, and gather information about DNS records for your domain. To execute an nslookup command, enter the following in Command Prompt:



Reverse DNS Lookup:

If you possess an IP address and need to find the corresponding domain name, a reverse DNS lookup is the answer. The process is similar to the previous example but in reverse:



Set Command:

The set command is ideal for retrieving the nameserver for a domain or configuring specific parameters in the command line. This example demonstrates how to set the query type to "ns" (nameserver):


>set q=ns
