Abstract

Disclosed are an NAT64 resource acquisition method and acquisition/distribution apparatus. The NAT64 resource acquisition method comprises: sending a router solicitation (RS) message to a server end device, and receiving a first router advertisement (RA) message from the server end device, wherein information carried in the RS message comprises: a pref64::/n resource request, and information carried in the first RA message comprises: pref64::/n resource information distributed according to the pref64::/n resource request; and/or, receiving a second RA message sent actively by the server end device, wherein information carried in the second RA message comprises: actively distributed pref64::/n resource information. By means of the present invention, effects of reducing complexity of maintenance and enhancing convenience in transition to IPv6 only are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a NAT64 resource acquisition method and an acquisition / allocation device. Background technique [0002] At present, Network Address Translation (NAT for short) in related technologies belongs to the technology of accessing the wide area network (WAN), and is a conversion technology for converting private (reserved) addresses into legal Internet Protocol (IP) addresses. It is widely used in various types of Internet access methods and various types of networks. NAT can solve the problem of lack of IP addresses. [0003] With the exhaustion of IPv4 address resources and the gradual deployment of IPv6 networks, the large-scale IPv4 networks and newly established IPv6 networks in the network make it urgent for operators to solve the problems between various IPv6 networks and IPv4 networks when IPv6 / IPv4 coexist. exchange of visits. NAT64 technology and DNS64 technology are a pra...
