Provided are a method and apparatus for constructing a peer-to-peer (P2P) overlay network. The method of constructing a peer-to-peer (P2P) overlay network to obtain ID values of a plurality of nodes using a distributed hash table (DHT) and registering a node wishing to join the P2P overlay network where the plurality of nodes are sequentially located based on the obtained ID values, includes: (a) transmitting a join request message from the node wishing to join the P2P overlay network to a key node of the P2P overlay network; (b) a first node that received the join request message determining whether an ID value of the node wishing to join the P2P overlay network is a between value of an ID value of the first node and an ID value of a second node next to the first node, while sequentially transmitting the join request message to the plurality of nodes; and (c), if the first node determines that the ID value of the node wishing to join the P2P overlay network is the between value, registering the node wishing to join the P2P overlay network between the first and second nodes. Therefore, it is possible to more easily and efficiently search for sharing resources stored by each of the nodes.
