What is the effect of ipconfig /renew?

• A. Requests new IP lease from DHCP server.
• B. Releases the current IP address.
• C. Displays DNS cache.
• D. Pings the default gateway.

Answer: (A)

The main idea here is DHCP lease renewal. Running ipconfig /renew asks the DHCP server to renew the IP address lease for each network adapter that is configured to obtain an IP automatically. This can refresh the binding and, depending on the server, may assign the same or a different IP address. It’s different from releasing the address (which frees it back to the DHCP pool) and from displaying DNS cache or pinging the gateway, both of which are unrelated actions. If you target a specific adapter, only that one is renewed.
