Conflicts Information Fields

Field	Description
IP Address	The IP address that has been detected as a duplicate.
Detection Method	The method used to detect the conflict, which is one of the following: Gratuitous ARP: The DHCP (Dynamic Host Configuration Protocol) client detected the conflict by broadcasting an ARP request to the address specified in the DHCP offer message sent by the server. If the client receives a reply to the ARP request, it declines the offer and reports the conflict. Ping: The server detected the conflict by sending an ICMP (Internet Control Message Protocol) echo message (ping) to the IP address before offering it to the DHCP client. If the server receives a response to the ping, the address is considered to be in conflict and is removed from the pool. Host Declined: The server received a DHCPDECLINE message from the host. A DHCPDECLINE message indicates that the host has discovered that the IP address is already in use on the network.
Detection Time	The time when the conflict was detected in days, hours, minutes and seconds since the system was last rebooted (that is, system up time).
Clear Entries (Button)	Clears all of the address conflict entries.
