Description
The IP address that has been detected as a duplicate.
The method used to detect the conflict, which is one of the following:
Gratuitous ARP: The DHCP 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 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.
The time when the conflict was detected in days, hours, minutes and
seconds since the system was last reset (i.e., system up time).
