BitLocker is an encryption solution for volumes initially made available in Windows Vista and Windows Server 2008, respectively. BitLocker Drive Encryption (BDE) may have some of the same issues that plague other Microsoft products, but many individuals use it all over the world to keep their data secure when it is dormant.

What is PowerShell?

Microsoft created PowerShell as an object-oriented automation engine and scripting language with an interactive command-line shell to assist IT professionals in automating administrative activities and configuring systems. PowerShell is part of the PowerShell family of tools.

In contrast to most command-line shells, which are built on text, PowerShell, based on the.NET framework, works with objects. Because of its scripting features, PowerShell is used as a tool for automation by system administrators working in internal IT departments and other entities such as managed service providers. These administrators are employed in both internal and external IT departments.

The original version of PowerShell was a closed-source solution exclusive to the Windows platform. In 2016, Microsoft released PowerShell as open-source software and made it compatible with macOS and Linux. (more…)

Introduction

The ipconfig command updates DHCP and DNS settings and displays details about your network configuration. The ipconfig command by default shows the default gateway, subnet mask, and IP address. However, you may extract much more information from it with the right parameters.
The ipconfig command and its various options will be explained in this article.

How to Open Command Prompt

You must open the Command Prompt window in order to use this tool. The Command Prompt window can be opened in one of three ways:

1. Use the Windows search feature to look for “cmd.”
2. Right-click the Start button and choose Command Prompt.
3. Press WinKey + R on your keyboard, and then type cmd in the Run window.

How to use the ipconfig command

So, let us start with something easy, like how to use the ipconfig command.
After CMD is opened. Type:

ipconfig

This will show you the most basic information about your network from your network adapters.

As you can see from the above screenshot, the Command will tell you about each network adapter on your computer. In this case, we have a wired (ethernet) network adapter and a wireless (Wi-Fi) network adapter. If you have a VPN client, it will also show up as a network adapter.

all Option

The Command displays only the most basic network information without using any parameters. But by default, no information on the DNS and DHCP servers is shown. You must use the /all argument to display all the details about your network adapter.

ipconfig /all

The following details will be returned for each network adapter in your device:

The ipconfig /all tool is frequently used to diagnose issues with network connections.

release Option

The ipconfig command can reset or update your network settings and display information about your configuration. You can ask the DHCP server for a new IP address if DHCP is enabled on your network card.
To start, the current IP address must be made public. Doing this will let the DHCP server know that we no longer want to use the provided IP Address.

ipconfig /release

The Command will, by default, release the IP addresses for every network interface. Additionally, a single network adapter may be specified. It would help if you input the name of the adapter that you see here in the output of ipconfig in order to accomplish this:

ipconfig /release Wireless*

renew Option

After releasing an IP Address, a new one must be requested from the DHCP server. This is possible using the Ipconfig /renew Command:

ipconfig /renew

If the renewal was successful, you would receive the same output as the ipconfig command, which includes an overview of your new IP Address, subnet mask, and gateway.
Once more, we can specify a single network adapter by providing the adapter’s name.

ipconfig /renew Wireless*

Display DNS Command

Your computer maintains a local cache of all visited DNS records. This cache quickly translates domain names to their corresponding IP addresses. This eliminates the need for your computer to contact the DNS server each time you visit Google.com, for example:
You can perform the command ipconfig /displaydns to view the DNS cache’s contents.
This will display each DNS record in the DNS cache:

ipconfig /displaydns

Flush DNS Command

Occasionally, your DNS Cache may contain obsolete records, resulting in DNS-related errors (unable to reach websites, for example). Typically, this can be resolved by executing the flush DNS Command.

ipconfig /flushdns

The ipconfig /flushdns command clears your DNS Cache. This is risk-free; your computer will simply request updated DNS records from the DNS servers.
