What is the command to flush the local DNS cache?

Flushing the local DNS cache is an essential troubleshooting step that can resolve issues like outdated or incorrect DNS information on a Windows machine. The command used for this purpose is specifically designed to clear the DNS resolver cache stored on the local system.

When you execute the command to flush the DNS cache, it removes all entries that may be causing conflicts or delays in resolving domain names to IP addresses. The result is that the next time a DNS query is made, it retrieves the latest DNS information from the configured DNS server rather than relying on potentially stale data.

The other commands have different functions: releasing and renewing an IP address involve managing DHCP leases, while the command to display all IP configuration details provides an overview of the network settings but does not interact with the DNS cache. Hence, the choice that specifically targets the DNS cache is the correct answer.
