System and method for integrated management of terminal information in IPv6 environment

A method for integrated management of terminal information in an IPv6 environment, which is performed in an apparatus for integrated management of terminal information, the method comprising:

• receiving, by a first data collection unit, address information of at least one terminal acquired by at least one ND cache from the at least one ND cache;
• receiving, by a second data collection unit, IPv6 address allocation information allocated to the at least one terminal by a DHCPv6 server from the DHCPv6 server;
• receiving, by a third data collection unit, IPv4 address allocation information about each of the at least one terminal, including an IPv4 address and a MAC address which are allocated to each of the at least one terminal, from an IPv4 address allocation information database;
• generating and managing, by a data linkage/storage unit, integrated terminal management information by linking the address information and the IPv6 address allocation information using, as a key value, an IPv6 address commonly stored in the address information received from the ND cache and the IPv6 address allocation information received from the DHCPv6 server;
• and
• linking and storing, by the data linkage/storage unit, the IPv4 address allocation information and the integrated terminal management information using the MAC address included in the IPv4 address allocation information as a key value.
