Disclosed is an IP management method for protecting a specific IP address on a network, which including the steps of: (a) detecting an ARP packet transmitted on the network; (b) extracting a sender address from the ARP packet; (c) determining if a transmission IP address of the sender address has been set as a protection IP; (d) when the transmission IP address has been set as the protection IP, determining if a transmission MAC address of the sender address is equal to a designated MAC address capable of using the transmission IP address; (e) when the transmission MAC address is different from the designated MAC address, transmitting an ARP packet to the sender address; and (f) transmitting a compensation packet to all devices on the network, wherein the compensation packet allows an actually used MAC address of the transmission IP address to be equal to the designated MAC address.
