Herein, what is DHCP conflict detection?
Conflict detection can be used by either DHCP servers or clients to determine whether an IP address is already in use on the network before leasing or using the address. If the DHCP client detects a conflict, it will send a DHCP decline message (DHCPDECLINE) back to the DHCP server that offered the IP lease.
