The embodiment of the invention provides an internet protocol IP address conflict detection method and device, the method comprises: receiving a ARP message; if the source IP address of the received ARP message and a ARP item of the same IP address, then send at least one ARP request message, wherein, the the at least one ARP request message to the IP address to the ARP table of the IP address; and determine whether there is IP address conflict in the network according to the response to the ARP request message. IP address conflict detection method provided by the embodiment of the invention by sending the ARP request message active detection of possible IP address conflict in the network, IP address conflicts existing in the network and that, which can IP address conflict in the network when you take action in order to avoid the normal network communication is affected, improve the reliability of the network.
