Apparatus for supplying mobile ipv6

An apparatus for providing mobile IPv6 is provided to quickly sense when a mobile node moves to a new link, transmit packets necessary for binding, and quickly process a response packet by realizing hardware for providing the mobile IPv 6, thereby efficiently supporting mobility. An apparatus(300) for providing mobile IPv6 comprises the followings: a mobile reception processor(323) which outputs home addresses of a mobile node and correspondent node and header information related to mobility according to whether a received packet is a binding packet or a data packet; a binding cache(302) and a binding update storage(303) for storing binding information that the mobile node has received and transmitted; and a binding receiver(325) which receives a binding message generated by the correspondent node, receives home address information of the mobile node and correspondent node from the mobile reception processor(323) and provides information about the binding message to the bonding cache(302) and binding update storage(303).
