Method for IPv4 internal private network to visit IPv6 network and router thereof

Abstract

The invention discloses a method of visiting IPv6 network with personal network in IPv4, which comprises starting a boundary route between personal network in IPv4 and IPv6 network, achieving NAT-PT function, allocating IPv4 address of a host machine of IPv6 network in the IPv4 network according to relative transformation rule and condition, allocating IPv6 address of a host machine of personal network in IPv4 in the IPv6 network, when the host machine of the personal network in IPv4 sends message visit to the host machine of IPv6 network, and when the host machine of the IPV6 network returns response message to the host machine of the personal network in IPv4, achieving the exchange of destination address and origin address of each message between IPv4 address and IPv6 address. The invention also discloses a boundary route. The invention enables a host machine of personal network in IPv4 to directly visit a host machine of IPv6 network, which is easy to realize.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and a router for directly accessing an IPv6 network through a NAT-PT within an IPv4 internal private network. Background technique [0002] At present, with the rapid development of the network, more and more problems are exposed in the IPv4 network, such as the lack of IPv4 addresses, the expansion of the routing table, security issues, etc. development of. Since the establishment of the IPv6 standard in 1992, the IPv6 standard system has been basically perfected, which has promoted IPv6 from the laboratory to the actual network. The research on IPv6 has shifted from the theoretical level to the application level exploration, thus further promoting the development of IPv6 technology, which can effectively solve the problems existing in IPv4. However, due to the large-scale application of the IPv4 network at present, it needs a certain transition period to convert it ...

AI Technical Summary

Problems solved by technology

However, the hosts of these internal private networks cannot directly access the IPv6 network, so there are certain limitations

[0009] To sum up, it can be seen that the technology of accessing the IPv6 network from the IPv4 internal private network in the prior art obviously has inconvenience and defects in actual use, so it is necessary to improve it.
