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 cannot be avoided, such as the application layer gateway (Application Level Gateway, ALG) does not Perfect, currently only supports fewer network protocols and cannot parse encrypted application layer data, etc.

Abstract

The embodiment of the present invention provides a method for allocating addresses, including: configuring a DNS server and a DNS64 server for the same access point of the gateway; judging whether the terminal requesting to access the network server supports the IPv4 protocol stack; Allocate a DNS address pointing to the DNS server; wherein, the DNS server is used to send the IPv4 address and / or IPv6 address of the network server to the terminal, and the DNS64 server is used to convert the IPv4 address that only supports the IPv4 protocol stack to the terminal. The IPv4 address of the web server is synthesized into an IPv6 address and sent to the terminal. The embodiment of the invention also discloses a device and system for allocating addresses. By adopting the present invention, different addresses can be assigned to the terminal according to the type of protocol stack supported by the terminal, so that the dual-stack terminal always accesses the IPv4 server with the IPv4 protocol stack, which reduces the cost of the operator, improves the user experience, and avoids various problems of NAT64. kind of defect.

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, the fourth version of the Internet Protocol (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 addresses and IPv6 addresses) Scenario of accessing an IPv4 network server (only providing IPv4 protocol stack services). In this scenario, IPv6 and IPv4 Network Address Translation (Netwo...
