Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the following will give a clear and complete description of the present application in conjunction with specific embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] An Internet Protocol (IP) address for interconnection between networks identifies a terminal user in the computer Internet. End users will use domain name access instead of IP address. In order to realize domain name access, domain name resolution is required between the two. The domain name system is designed as a distributed database of Transmission Control Protocol / Internet Prot...

Abstract

The invention discloses a method and equipment for realizing a DNS and a storage medium, and the method comprises the steps: enabling a programmable switch to receive a message sent by a host, and judging whether the message is a domain name system DNS request message or not; if yes, querying whether an IP address inquired by the DNS request message exists in a chip hardware table item or not, wherein the chip hardware table item is stored in the switch; if yes, returning the IP address to the host; if not, uploading the DNS request message to a local domain name server for query; receiving a DNS response message which is returned by the local domain name server and contains the IP address; analyzing the DNS response message, storing a mapping relationship between a domain name contained in the DNS request message and an IP address in the chip hardware table item according to the IP address obtained by analysis, and returning the IP address to the host.

Description

technical field [0001] The present application relates to the field of domain name resolution, in particular to a method, device and storage medium for realizing DNS. Background technique [0002] An IP address identifies an end user in the computer internet. End users will use domain name access instead of IP address. In order to realize domain name access, domain name resolution is required between the two. [0003] Domain Name System (Domain Name System, DNS) is the link connecting the entire Internet application layer and network layer. Its main function is to realize the conversion between IP addresses and domain names to locate and identify Internet resources. mail, etc.) to function properly. [0004] However, the existing domain name resolution often has problems such as slow response speed of visiting websites due to small network bandwidth and large number of user visits, which affects user experience. Contents of the invention [0005] This application provi...
