PROBLEM TO BE SOLVED: To provide a communication method for a network for updating a network entry code efficiently and dynamically, in a P2P network having network entry codes variable according to increase or decrease of nodes joining in the network. SOLUTION: The communication method for the network is provided, by which the P2P network transmits a message with a network entry code for a transmission node included, compares the network entry code included in a reception message with a network entry code for a reception node, enables transmission if they match, and updates the network entry code if they do not match, thus making the network entry codes match, so that the network entry codes can be updated efficiently and dynamically at optimum timing and a high security function can be secured.
