Which command sequence would you use to release and renew an IP address on Windows?

• A. ipconfig /release followed by ipconfig /renew
• B. ipconfig /renew
• C. netsh winsock reset
• D. ping 192.168.1.1

Answer: (A)

Releasing and renewing an IP address refreshes the DHCP lease on the Windows machine. Releasing clears the current IP configuration from the adapter, signaling to the DHCP server that the address is no longer in use. After that, renewing requests a new IP lease, or a refreshed lease, from the DHCP server. This two-step sequence—release first, then renew—ensures you abandon the old address before obtaining a new one, which can resolve issues like IP conflicts or stale leases. The other commands don’t perform this combination: renewing alone requests a new lease without explicitly relinquishing the current one, resetting the Winsock stack affects the network stack rather than DHCP leases, and ping only checks connectivity and changes nothing about IP configuration.
