What is the purpose of the ipconfig /release command?

The ipconfig /release command is utilized to release the current DHCP (Dynamic Host Configuration Protocol) lease for all network adapters on a computer. When this command is executed, it informs the DHCP server that the IP address currently assigned to the device is no longer needed, allowing that address to be returned to the pool of available IP addresses. This action is particularly useful in scenarios where you want to change the IP address assigned to the device or troubleshoot network connectivity issues. Once the IP is released, you can follow it up with the ipconfig /renew command to request a new IP address from the DHCP server.

The other options do not accurately describe the function of the command. Resetting local network settings generally involves a more comprehensive set of changes than just releasing an IP address. Showing all active network connections pertains to different commands that display network communications rather than lease management. Clearing the DNS cache is accomplished using a separate command and does not relate to IP address leases at all.
