Object
notification
This notification signifies that a duplicate IPv4 address has been detected. The DHCP server can detect this condition through the ping-before-offer mechanism. Alternatively, the client may have sent a DHCPDECLINE back to the server; this is assumed to be the result of the client detecting that the address was in use. In either case, the DHCP server marks the IPv4 address as unavailable for leasing to clients. The cDhcpv4ServerNotifyClientOrServerDetected object indicates whether the client or server detected this condition.
