How to release and renew an IP address

If you work in IT, there are a few things you need to know no matter what. These are the basic skills that anyone in the IT industry needs. One of these skills is the ability to renew and release IP addresses.

There’s a lot to do in your IT career, and it’s really useful for reconnecting your computer to the Internet or local LAN. Renewing your IP address can also help you resolve IP conflicts.

Renew the IP address

To renew your IP address, go to BeginningFollowing Jogging and the guy CMD, to open a new command prompt window. In newer versions of Windows, just click Start and type CMD.

Now type the following command:

 ipconfig / renew 

Regardless of which network adapters are currently connected to the computer, they will be shut down and their addresses will be renewed using the DHCP server. If you can’t recover your IP address, you can read my previous post on troubleshooting The IP address cannot be renewed .

Note that you can display all IP configuration information using the parameter / everyone .

 ipconfig / all 

Release the IP address

To release the IP address, type the following command:

 ipconfig / release 

This command will release the IP address of all connected adapters. If you often have to release and renew an IP address, it may be easier to create a batch file and add the commands there. Here’s what you’ll copy and paste into your file:

 ipconfig / release ipconfig / renew pause 

Save the file anywhere off the desktop, then right-click on it and choose command send toDesktop (Create shortcut ). Double-click the shortcut to run the script that you can see in the command window.

DNS resolver commands

Note that you can also refresh all DHCP leases and re-register DNS names using the parameter registered dns .

 ipconfig / registerdns 

If you want to clear the DNS resolution cache on the local machine, you can use the parameter flushdns .

 ipconfig / flushdns 

To view the contents of the DNS resolver cache, use the parameter displaydns .

 ipconfig / displaydns
