Abstract

The invention discloses a NAT64 resource acquisition method and an acquisition / allocation device. Wherein, the method for acquiring NAT64 resources includes: sending a router request RS message to the server-side device, and receiving a first router advertisement RA message from the server-side device, wherein the information carried in the RS message includes: pref64:: / n Resource request, the information carried in the first RA message includes: pref64:: / n resource information allocated according to the pref64:: / n resource request; and / or, receiving the second RA message actively sent by the server-side device, wherein the first The information carried in the 2-RA message includes: pref64:: / n resource information actively allocated. Through the present invention, the complexity of maintenance is reduced and the convenience of transitioning to pure IPv6 is enhanced.

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...
