Title:
IPv4 TO IPv6 ADDRESSES REPLACING METHOD AND IPv4 TO IPv6 COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP3635223
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress a conventional problem that one IPv4 terminal dominates virtual IPv4 addresses and another IPv4 terminal can not obtain a virtual IPv4 address to be allocated to an IPv6 terminal in a communication mode in which the IPv6 address of the IPv6 terminal is specified by a virtual IPv4 address that are virtually assigned to an IPv6 terminal, thus enabling communication between the IPv4 terminal and the IPv6 terminal.
SOLUTION: When dynamically assigning a virtual IPv4 address to the IPv6 terminal, the IPv4 address of the IPv4 terminal in communication is also held, thus making it possible for each IPv4 terminal in communication to allocate the virtual IPv4 address to the IPv6 terminal.
