Abstract: PURPOSE: An ARP(Address Resolution Protocol) attack prevention method of a node within a network is provided to easily recognize a MAC address of a different node connected to a network through a MAC address within a transmitted and received packet by a node where an agent including an IDD(Intermediate Device Driver) and an IDD controller is installed. CONSTITUTION: A transmission node(210) broadcasts an initialization message including a MAC address and an IP address to all other nodes connected to a network(S220). The transmission node and a node(230) receiving the initialization message initializes an pre-stored ARP table(S240). The transmission node and the node receiving the initialization message reconstructs an ARP table based on MAC addresses and IP addresses of the all nodes according to the broadcasting of the MAC address and the IP address from the all nodes connected with the network(S250). [Reference numerals] (210) Transmission node; (230) Another node in a network; (AA) Yes; (BB) No; (S210) Connecting to the network; (S220) Broadcasting an initialization message including own MAC address and IP address; (S230) Broadcasting an initialization response message including own MAC address and IP address; (S240) Initializing an ARP table; (S250) Reconstructing an identical ARP table; (S260) Exchanging packets; (S270) Setting an initialization time; (S280) Initialization time=0?
