Problems solved by technology

[0004] This increases the service pressure of NAT64 and the expansion cost of the operator, which will affect the user experience due to the increase of access delay and the decrease of access reliability; in addition, the defects of NAT64 itself, such as the application layer gateway (Application Level Gateway, ALG ) is imperfect, currently only supports few network protocols and cannot parse encrypted application layer data, etc.

Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] figure 1 Schematic flow chart of the first embodiment of the method for allocating addresses in the present invention; in this embodiment, the method includes the following steps:

[0034] S101. Configure a DNS server and a DNS64 server for the same access point of the gateway at the same time.

[0035] This step is the basis for the subsequent implementation of DNS address allocation according to the type of protocol stack supported by the terminal. Where...

Abstract

The embodiment of the invention provides a method for distributing addresses, comprising the following steps : as a gateway of an access point with the configuration server and dns server for dns 64; judging whether requests access to a network server, whether the terminal supports the IPv4 protocol stack; if yes, the terminal is allocated to the dns server dns address; wherein the dns server for transmitting the network server of an IPv4 address and or the IPv6 address to the terminal, the dns server only 64 for supporting IPv4 protocol stack of the IPv6 network server of the IPv4 address to IPv6 address is sent to the terminal. The embodiment of the invention also discloses an address allocation device and system. By adopting the method, according to the type of the terminal supports the protocol stack to allocate the different address, the dual stack terminals to the IPv4 protocol stack access IPv4 server, and reduces the cost of an operator, improves the user experience, and avoids the defects of NAT 64.

Description

technical field [0001] The present invention relates to the technical field of mobile Internet, in particular to a method, device and system for allocating addresses. Background technique [0002] In the existing mobile Internet architecture, the sixth version of the Internet Protocol (Internet Protocol version 6, IPv6) has the advantages of large address space, small routing table, and high security, so it will gradually replace the existing protocol, namely the fourth version of the Internet Protocol (IPv6). Internet Protocol version 4, IPv4). However, in the current mobile Internet, there are still many user terminals (User Equipment, UE) with IPv4 addresses and servers with IPv4 addresses. In the early stage of IPv6 evolution, there will be a large number of dual-stack terminals (with both IPv4 ) to access an IPv4 network server (which only provides IPv4 protocol stack services). In this scenario, IPv6 and IPv4 Network Address Translation (Network Address Translation I...
