Which command is used to release and renew a DHCP lease on a Windows workstation?

The command used to release and renew a DHCP lease on a Windows workstation is "ipconfig /renew". This command specifically instructs the DHCP client on the Windows system to request a new IP address from the DHCP server, effectively renewing the lease.

When a workstation initially connects to a network, it is assigned an IP address from a DHCP server for a limited time, known as a lease. If the lease time is about to expire or if the user wants to refresh their IP configuration, "ipconfig /renew" is utilized. This command communicates with the DHCP server to obtain a new IP address or to renew the existing lease if possible.

While "ipconfig /release" is a command that is related, it is used solely to release the current IP address back to the DHCP server, without renewing it. The options "dhcprelease" and "netsh renew" do not apply to Windows in this context, as they are not standard commands for managing DHCP leases in the Windows operating system. Therefore, using "ipconfig /renew" correctly accomplishes the task of renewing the DHCP lease.
