Problems solved by technology

[0014] In the above solution, it is necessary to manually configure the translation policy on the NAT64 device. The IPv6 prefix referenced in the policy and the prefix used to synthesize the IPv6 address on DNS64 must be consistent, otherwise the translation cannot be performed.
[0015] In actual use, manually configuring the above-mentioned conversion strategies on the NAT64 device requires a huge workload, and automatic operation and maintenance cannot be realized. The efficiency is low and error-prone, and if the above-mentioned conversion strategies are not synchronized in time or are synchronized incorrectly, it will cause network failures. Interruption, unable to ensure timely and accurate forwarding of cross-protocol network packets

Abstract

The present application provides a message forwarding method and device, a domain name address query method and device, an electronic device, and a computer-readable medium. Wherein, the message forwarding method includes: receiving the first address query request for the target domain name sent by the client, if the corresponding network address is not found locally, sending the second address query request to the domain name system, and receiving the returned A second response message including the first network address and address translation information, sending the first response message to the client, and after receiving the service message sent by the client whose destination address is the first network address, Translating the destination address of the service packet into the second network address according to the address translation information, and sending the service packet after the destination address translation to the target server. The method can realize the automatic operation and maintenance of the network address translation equipment, and ensure the timely and accurate forwarding of cross-protocol network messages.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a message forwarding method and device, a domain name address query method and device, an electronic device, and a computer-readable medium. Background technique [0002] With the development of the Internet, IPv4 (Internet Protocol Version 4) addresses have been gradually exhausted, and the IPv6 (Internet Protocol Version 6) network will eventually replace the existing IPv4 as the backbone network of the Internet. However, due to many reasons such as cost and technical limitations, IPv4 equipment will still exist for a long time. Therefore, the deployment of IPv6 is a smooth evolution process, and IPv6 and IPv4 will coexist for a long time. [0003] In order to solve the problem of IPv6 clients accessing the IPv4 network, the prior art provides NAT64 (NetworkAddress Translation for IPv6-IPv4, the network address translation from the sixth version of the Internet P...
