Abstract: An apparatus and method for controlling network access are provided.

Abstract: Provided are an apparatus and method for integrated management of terminal information in an IPv6 environment. The apparatus for integrated management of terminal information in the IPv6 environment includes a first data collection unit that receives, from at least one Neighbor Discovery (ND) cache, address information of at least one terminal acquired by the ND cache, a second data collection unit that receives, from a DHCPv6 server, IPv6 address allocation information allocated to the at least one terminal by the DHCPv6 server, and a data linkage/storage unit that generates integrated terminal management information linked with the received address information and IPv6 address allocation information, and stores and manages the generated integrated terminal management information.

Abstract: A policy server receives an access policy information request message, and authenticates the request. When the authentication is successful, an access policy storage is accessed to obtain access policy information corresponding to the source of the message. The server outputs the corresponding access policy information. The information includes an IPv6 address for use, at the source, as a new source address. The information may also include a terminal address setting function, a rebooting option adding function upon terminal address setting, a default gateway setting function, a domain name service (DNS) server address setting function, a tunnel function on or off function, a neighbor cache clearing function, and/or a privacy extension on or off function.
