Release and Renew IP Address (2024 Tutorial)

Written by Robert Bailey

Release and Renew IP address to repair connectivity issues

Every computer connected to a network has its Internet Protocol address (IP address) to identify and communicate with other computers. While most computers automatically obtain an IP address assigned by a server running a service called Dynamic Host Configuration Protocol (DHCP), some IP addresses require manual configuration (each computer is set manually, including its IP address on a given network). Usually, this process of obtaining/assigning an address is automatic. However, there may be cases where it does not work as it should.

Releasing/updating the IP address is an action that can solve some connectivity problems. You can do this regardless of your OS. So in Windows, you can do it through the command line, while MacOS offers a graphical interface. Removing the old IP address can quickly solve connectivity problems. The first command for Windows, which we will explain in the text, is ipconfig /release. It makes the system forget your “old” IP and mark it as free on the DHCP server. The second, ipconfig /renew, ask the DHCP server for a new IP address for your device.

“Any workarounds to logging into Fortnite right now? Been trying non-stop, but haven’t been able to login since the event. Still really looking forward to trying out those lightsabers!!”, — writes Twitter user @NickEh30.

These commands are used widely for fixing networking issues since they are working despite all changes in Windows done since Windows XP was released.

Release/Renew IP commands are usually finalized by the Flush DNS command, which releases the DNS cache and submits requests to apply new IP address data.

Refer to the tutorial below for releasing and renewing the IP address on Windows 11, 10, 8, 8.1, 7, Vista, XP, Mac, and Linux. Also, ensure your network adapter is tuned correctly to obtain an IP address automatically. Otherwise, the above-said commands won’t function well.
