Abstract: PURPOSE: An IPv6(Internet Protocol version 6)-IPv4 NAT-PT(Network Address Translation-Protocol Translation) method using an automatic port translation and a recording medium therefor are provided to prevent the waste of an idle time in which hosts of an IPv6 network wait until another address is released and enhance the utilization of an IPv4 address pool by automatically translating an address translation method into a port translation method when a use rate of an address pool to be translated is greater than a specific threshold value. CONSTITUTION: If IPv6 packets are transmitted from IPv6 hosts, an IPv6-IPv4 address translation device receives the IPv6 packets and compares a use rate of an IPv4 address pool with a predetermined threshold value for judging whether the use rate of the address pool is less than the predetermined threshold value(S11). If the use rate of the address pool is same to or greater than the predetermined threshold value, the IPv6-IPv4 address translation device automatically translates an address translation method into a port translation method for translating the IPv6 packets into IPv4 packets and transmitting the IPv4 packets(S15).

Abstract translation: 目的：提供使用自动端口转换及其记录介质的IPv6（因特网协议版本6）-IPv4 NAT-PT（网络地址转换 - 协议翻译）方法，以防止浪费IPv6的主机的空闲时间 网络等待直到另一地址被释放，并且当要转换的地址池的使用率大于特定阈值时，通过将地址转换方法自动转换为端口转换方法来增强IPv4地址池的利用率。 规定：如果IPv6报文是从IPv6主机发送的，则IPv6-IPv4地址转换装置接收IPv6报文，并将IPv4地址池的使用率与预定阈值进行比较，判断地址池的使用率是否小于 预定阈值（S11）。 如果地址池的使用率等于或大于预定阈值，则IPv6-IPv4地址转换设备将地址转换方法自动转换为用于将IPv6分组转换为IPv4分组并发送IPv4分组的端口转换方法 （S15）。
