Problems solved by technology

For example, if the accessed service only supports IPv6 addresses, the domain name server will definitely fail when responding to the first DNS resolution request in A mode, and will only receive the second DNS resolution request in AAAA mode initiated by the dual-stack terminal. will correctly respond to IPv6 format addresses, then the efficiency of dual-stack terminals will be affected when accessing IPv6 services
Conversely, if DNS requests are always made in the AAAA mode first, and then in the A mode, then the effect is not ideal when accessing IPv4 services

Embodiment Construction

[0032] The technical solutions of the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0033] figure 1 It is the application networking diagram of the present invention. As shown in the figure, the terminal supports IPv4 / IPv6 dual stack, and can access the IPv4 server or IPv6 server after performing domain name resolution through the DNS server.

[0034] In this IPv4 / IPv6 dual-stack environment, in order to improve the efficiency of domain name resolution when the terminal accesses the network for service access, the present invention provides a terminal that supports IPv4 / IPv6 dual-stack, such as figure 2 As shown, the terminal includes:

[0035] The application module is used to trigger the domain name resolution module when the application service requiring domain name resolution is started;

[0036] There are many application services that require domain name resolution, such as SNTP (time service...

Abstract

The invention provides a method and a terminal for improving domain name resolution efficiency. The method is realized by a terminal which supports an IPv4 / IPv6 dual stack, and comprises the steps that: the terminal initiates a domain name resolution request to a domain name system server; and the terminal records a first format corresponding to the initiated domain name resolution request as a default initiating format of a current domain name resolution request when receiving a normal response. The method and terminal have the function of dynamically adapting to a network environment to a certain extent and can improve the efficiency of the domain name request, so that the smoothness of the whole business access is improved.

Description

technical field [0001] The invention relates to a communication network system, in particular to a method and a terminal for improving domain name resolution efficiency in an IPv4 / IPv6 dual-stack environment. Background technique [0002] Although IPv6 has not yet been applied on a large scale, with the rapid shortage of global IP addresses and business needs, the rapid development and gradual popularization of IPv6 has become inevitable. But how to transition is also an important issue, and the IPv4 / IPv6 dual-stack approach is a common transition mechanism. [0003] For the dual-stack method, when the terminal initiates a service, it will inevitably involve the selection of the IP method, and generally speaking, the service access uses the domain name method, so domain name resolution becomes the key point. [0004] In the IPv4 and IPv6 dual-stack scenario, when a terminal initiates a domain name request, there will be two DNS (Domain Name System) resolution request method...
