Abstract

The invention provides a method and equipment for the access of an Internet protocol version 4 (IPv4) private network to an Internet protocol version 6 (IPv6) network, and relates to the technical field of Internet. The method comprises the following steps of: receiving an IPv6 message; selecting a private network IPv4 address and a port for the IPv6 message from an IPv4 private network address pool according to a header of the IPv6 message, and allocating an IPv4 private network destination IPv4 address and a destination port to the IPv6 message; converting the IPv6 message into a target IPv4 message; and forwarding the target IPv4 message to an IPv4 server corresponding to the destination IPv4 address and the destination port of the target IPv4 message. According to the method and the equipment, communication with an IPv6 public network can be realized under the condition of not changing any conventional configuration of each IPv4 server in an enterprise when the portal of the IPv4 private network of the enterprise is the IPv6 public network, and the network deployment cost is low.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and access equipment for realizing an IPv4 private network accessing an IPv6 network. Background technique [0002] With the increasing development of the Internet, the existing IPv4 (Internet Protocol version 4, Internet Protocol version 4) addresses are already in short supply, and it is impossible to avoid the problem that IPv4 addresses are exhausted. IPv6 (Internet Protocol version 6, Internet Protocol version 6) with 128-bit IP addresses has completely solved the problem of insufficient IPv4 addresses, and has obvious improvements in address capacity, security, network management, mobility, and service quality. A core standard adopted by a generation of Internet protocols. [0003] However, since the IPv4 network has developed very maturely, the IPv4 network is so huge that it takes a long time to gradually transition from the IPv4 network to the IPv6 network...
