Explanation

An IP conflict means two devices on the network have been assigned the same IP address. To resolve this on a DHCP client, the correct procedure is to first run 'ipconfig /release' to relinquish the current (conflicting) IP address back to the DHCP server, then run 'ipconfig /renew' to request a new, non-conflicting IP address from the DHCP server. These two commands work together as the standard fix. 'Ipconfig /all' only displays configuration information and does not fix anything. 'Ipconfig /flushdns' clears the DNS resolver cache and is unrelated to IP address conflicts. 'Ipconfig /registerdns' refreshes DNS registrations and leases, also unrelated to IP conflicts.
