Abstract
A method and device for efficiently using IPv4 public addresses applied to a core translator deployed between an IPv4 Internet and an IPv6 network, which maps an IPv4 public address into a first-type IPv6 address having a first-type prefix according to a transport layer protocol port range used by an IPv6 server in the IPv6 network, so that the IPv6 server uses the first-type IPv6 address to communicate with a client in the IPv4 Internet; and maps the IPv4 public address into a second-type IPv6 address having a second-type prefix according to a transport layer protocol port range used by an client in the IPv6 network, so that the client in the IPv6 network uses the second-type IPv6 address to communicate with a IPv4 server in the IPv4 Internet. The IPv6 server and the client in the IPv6 network can use the same IPv4 public address to provide different services.
