<p>Disclosed is an IP address allocator and method thereof for efficiently allocating the Internet Protocol version 6 (IPv6) IP address. Global prefixes allocated to terminals from a single packet data serving node (PDSN) are the same and the PDSN allocates an interface ID to the terminals, thereby preventing repetition of IP addresses between different terminals and allowing easy billing through the same global prefix. Also, since the interface ID is generated to the PDSN based on the global prefix received by the terminal, the load required for generating the interface ID by the PDSN is reduced. Therefore, the waste of IP addresses can be prevented since the IPv6 address is efficiently provided in the cable telephone or mobile telephone network, and the packets are efficiently performed based on the same global prefix since the same global prefix is allocated from a single PDSN.</p> |
