how to use Ipconfig command

Understanding ipconfig Commands and Their Uses

Ipconfig (short for Internet Protocol Configuration) is a command-line tool used to display and configure network settings on Windows operating systems. It provides valuable information about a computer’s network connections, such as IP addresses, subnet masks, default gateways, and DNS server addresses. In this article, we will explore various ipconfig commands and their uses, helping you gain a better understanding of how to manage network settings on a Windows system.

Basic Ipconfig Command

To use the ipconfig tool, open a command prompt on your Windows computer. You can do this by pressing the Windows key, typing “cmd,” and pressing Enter. Once the command prompt window is open, you can use the following basic ipconfig command:


Running this command without any additional options will display detailed information about all active network adapters on your system.

An IPv4 address is like a code made of 32 numbers, and it can have a little more than 4 billion different codes. But IPv6, which is newer, uses a code made of 128 numbers, and it can have a mind-boggling number of codes – even more than all the stars in the universe.

ipconfig /all

This command provides comprehensive information about all network adapters, including their physical and IP addresses, subnet masks, default gateways, DNS servers, and more. It is particularly useful when troubleshooting network-related issues.


ipconfig /release

This command releases the IP address assigned to a network adapter. This is useful when you want to release the current IP address before obtaining a new one from a DHCP server.

ipconfig /release

ipconfig /renew

After releasing an IP address, you can use this command to request a new IP address from a DHCP server. This can help resolve connectivity issues.

ipconfig /renew

ipconfig /flushdns

This command clears the DNS resolver cache, which can be helpful when troubleshooting DNS-related problems.

ipconfig /flushdns

ipconfig /displaydns

 Displays the contents of the DNS resolver cache, showing a list of resolved DNS names and their corresponding IP addresses.

ipconfig /displaydns

ipconfig /setclassid

This command sets the DHCP class ID for a specified network adapter. It is primarily used in advanced networking scenarios.

ipconfig /setclassid "Local Area Connection" My_Class_ID

ipconfig /showclassid

Displays the DHCP class ID for a specified network adapter.

ipconfig /showclassid "Local Area Connection"

ipconfig /registerdns

This command forces the computer to register its DNS records with the DNS server. It can be useful when troubleshooting DNS registration issues.

ipconfig /registerdns

ipconfig /allcompartments /all

Provides information about all network adapters, including those in different network compartments. Useful in advanced network configurations.

ipconfig /allcompartments /all

ipconfig /release6 /renew6

Similar to /release and /renew, but for IPv6 addresses. Useful for managing IPv6 connectivity.

ipconfig /release6
ipconfig /renew6


Understanding and utilizing ipconfig commands can be instrumental in managing and troubleshooting network connections on Windows operating systems. Whether you need to release and renew IP addresses, clear DNS caches, or retrieve detailed network configuration information, ipconfig offers a range of tools to help you maintain a healthy network environment.

Microsoft provides comprehensive documentation on ipconfig and its usage at Microsoft ipconfig documentation. Additionally, if you’re interested in Linux network configuration and commands, you can refer to the Linux documentation and resources available on various Linux distribution websites.

By mastering ipconfig commands, you’ll be better equipped to handle network-related issues and ensure smooth connectivity on your Windows system.
