Abstract

The invention discloses a method, a device and equipment for accessing an IPv4 outer chain and a computer medium, which are applied to an IPv6 client, and the method comprises the following steps: obtaining a URL (Uniform Resource Locator) of a target IPv4 outer chain, the URL of the target IPv4 outer chain consisting of an NAT64 gateway flow guide identifier and an initial IPv4 outer chain URL; Guiding the URL of the target IPv4 outer chain to an NAT64 gateway based on the NAT64 gateway guiding identifier; And receiving data information sent by the NAT64 gateway after accessing the URL of theinitial IPv4 outer chain. According to the IPv4 external link access method, device and equipment and the computer readable storage medium, the applicability is high.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically, relates to a method, device, equipment and computer medium for accessing IPv4 external links. Background technique [0002] During the transition from IPv4 to IPv6, when the IPv6 client browser accesses the legacy Web service system (such as IPv4 external link website), you may encounter an IPv6 skylight problem. The skylight problem is described as follows: When an IPv6 client accesses the IPv4 main website behind the NAT64 gateway, if the web page of the IPv4 main website carries an IPv4 external link URL (that is, uses the IPv4 protocol The webpage resources that do not belong to the main website can be accessed normally, such as pictures, audio or webpage subframes located on other websites), when the webpage reaches the IPv6 client for rendering, the IPv6 client will directly use the IPv6 protocol to access the IPv4 foreign Link URL. Under normal circu...
