What does ipconfig /release do?

• A. Removes the current IP address and negotiates a new lease.
• B. Renews DHCP lease automatically.
• C. Displays current IP configuration.
• D. Removes the current IP address but will not negotiate a new lease.

Answer: (D)

This tests understanding of how DHCP leases are managed with the ipconfig tool. The /release option releases the DHCP-assigned IP address from the selected network adapter, telling the DHCP client that the current lease is no longer in use. It does not contact the DHCP server to obtain a new address—that behavior belongs to the /renew command. After releasing, the adapter may have no IP address until you run a renew (which negotiates a new lease) or you configure a static address. So the description that matches releasing the IP address without negotiating a new lease is the correct one. If you run /renew, the client will reach out to the DHCP server to obtain a new lease.
