Embodiment 1

[0036] Such as figure 1 As shown, it is a schematic diagram of a domain name resolution method in Embodiment 1 of the present invention, and the method includes the following steps:

[0037] Step 101: The DNS server receives a domain name resolution request from a client, and the domain name resolution request carries domain name information.

[0038] In this step 101, when the DNS address set in the client network card properties is the address of the DNS server, when the client needs to access a certain website, it will send a domain name resolution request to the DNS server. Carries the domain name information of the website.

[0039] Step 102: When the domain name information is not a local domain name and the domain name resolution response corresponding to the domain name information is not cached locally, determine the forwarding DNS server to which the domain name resolution request belongs.

[0040] The DNS server can determine the ISP signed by the client in the fo...

Embodiment 2

[0066] Based on the same idea as that of Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a DNS server. The structure diagram of the DNS server 100 is as follows figure 2 As shown, it includes: a first receiving module 11 , a first determining module 12 , a first sending module 13 , a second receiving module 14 , and a second sending module 15 .

[0067] The first receiving module 11 is configured to receive a domain name resolution request from a client, wherein the domain name resolution request carries domain name information;

[0068] The first determining module 12 is configured to determine the forwarding domain name system DNS server to which the domain name resolution request belongs when the domain name information is not a local domain name and the domain name resolution response corresponding to the domain name information is not cached locally;

[0069] The first sending module 13 is configured to send the domain name resolutio...

Embodiment 3

[0079] Such as image 3 As shown, it is a schematic structural diagram of a DNS server in Embodiment 3 of the present invention, and the domain name resolution system includes: a DNS server 21 and a forwarding DNS server 22 .

[0080]The DNS server 21 is configured to receive a domain name resolution request from a client, the domain name resolution request carries domain name information, and when the domain name information is not a local domain name and there is no domain name resolution response corresponding to the domain name information cached locally, determine the domain name resolution request A forwarding DNS server to which the domain name resolution request belongs; sending the domain name resolution request to the determined forwarding DNS server, receiving a domain name resolution response, and sending the domain name resolution response to the client;

[0081] The forwarding DNS server 22 is configured to receive the domain name resolution request, perform a do...

Abstract

The invention discloses a domain name resolution method, a domain name system (DNS) server and a domain name resolution system. The domain name resolution method mainly comprises the following steps of receiving a domain name resolution request from a client; determining a forwarding DNS server to which the domain name resolution request belongs when no domain name resolution response corresponding to a domain name is cached in local; transmitting the domain name resolution request to a determined forwarding DNS server; and receiving the domain name resolution response obtained after the forwarding DNS server carries out the domain name resolution operation for the domain name information, and transmitting the domain name resolution response to the client. Since different domain name resolution requests are allocated to the forwarding DNS server to which the domain name resolution request belongs, and each forwarding DNS server targets the own domain name resolution request to carry out the domain name resolution, so that the restriction condition among different internet service providers (ISP) can be avoided, the domain name resolution speed is accelerated, the domain name resolution time is shorter, and the resolution efficiency is increased.

Description

technical field [0001] The invention relates to the field of IP (Internet Protocol, Internet Protocol) network, in particular to a domain name resolution method, a DNS server and a domain name resolution system. Background technique [0002] In the IP (Internet Protocol, Internet Protocol) network, the Domain Name System (Domain Name System, DNS) is one of the most critical basic services of the Internet, providing fundamental support for many network applications. Convert to an IP address recognizable by the network. The conversion between domain name and IP address is called domain name resolution, and the network host that performs domain name resolution can be called DNS server. Through the query service of the domain name system DNS server, the entrance of the required site or resource can be found, and then the site or resource can be accessed. [0003] In the prior art, DNS provides three domain name resolution methods: local query, cache query and iterative query. ...
