Problems solved by technology

[0006] 1. I don't know the relationship between the scheduled DNS egress address and the DNS ingress address, and the DNS ingress address is the DNS configured by the end user, so the scheduling is not directly for the end user, and there is a certain degree of blindness;
[0007] 2. If the user configures the wrong local DNS and is wrongly dispatched to another place, there is no easy detection method;
[0008] 3. If the local DNS is configured with a wrong troubleshooting strategy, there is no simple detection method
[0009] Scheduling technology in the existing CDN This kind of scheduling error is mainly geographical: that is, the server in B is configured for the user requesting content in A, so that the effect of quickly distributing content cannot be achieved

Embodiment 1

[0088] Such as figure 2 As shown, this embodiment provides a method for obtaining an Internet Protocol address, which is applied to an Internet Protocol address detection device, including:

[0089] S101. Receive the resolution request message of the original domain name sent by the client;

[0090] S102. Capture the request IP according to the received resolution request message of the original domain name;

[0091] S103. Return the captured request IP to the client.

[0092] The Internet protocol address acquisition method of this embodiment is applied to the content distribution network. In this embodiment, the original domain name is the designated IP address to obtain the registered domain name corresponding to the server, and the resolution request message of the original domain name sent by the client is sent to the designated IP address. Obtaining the server, wherein the resolution request message of the original domain name may include dig request and http / https re...

Embodiment 2

[0133] In this embodiment, the registered domain name of the DNS server is: dns.ali.com, and the DNS server is responsible for resolving the resolution request message of the domain name.

[0134] Such as Figure 6 As shown, this embodiment utilizes the DNS protocol to obtain the egress address of the local DNS:

[0135] The user initiates a dig request through the client, requesting access to the resolution request message of the original domain name of the domain name dns.ali.com of the DNS server;

[0136] The DNS server captures the request IP according to the resolution request message of the original domain name, and returns the captured request IP as an A record to the client. The relationship between the request IP and the local DNS configured by the user is the traction relationship between the egress address and the ingress address. So far, the user has obtained the local DNS egress address.

[0137] According to the obtained DNS egress address, the user can easily...

Embodiment 3

[0140] In the embodiment of the present invention, the DNS server, the registered domain name is: dns.ali.com, and the DNS server is responsible for resolving the resolution request message of the domain name, and the Web server, the registered domain name is: web.ali.com, and is authorized to the above-mentioned DNS The server resolves, and resolves to that web server.

[0141] Such as Figure 7 As shown, this embodiment uses the http protocol to obtain the egress address of the local DNS:

[0142] The user initiates an http request through the client, and requests to access the http request of the original domain name of the domain name web.ali.com of the web server;

[0143] The DNS server resolves to the corresponding web server according to the received http request of the original domain name; when the web server receives the original domain name request of web.ali.com, it generates a unique ID (for example: abc, the purpose of the ID is to distinguish different users ...

Abstract

The invention provides an Internet protocol address acquisition method, server and system. The method comprises the following steps: receiving an analysis request message of an original domain name sent by a client; capturing a request IP according to the received resolution request message of the original domain name; and returning the captured request IP to the client. According to the invention, the local DNS exit address can be rapidly detected, and the DNS exit address is fed back to the user, so that the user can troubleshoot the problem of the traction relationship between the local DNSentrance address and the DNS exit address, the operation threshold of obtaining the DNS exit address is reduced, and the scheduling error rate in the CDN is reduced.

Description

technical field [0001] The present invention relates to the technical field of CDN (Content Delivery Network, content distribution network) information processing, in particular to an Internet Protocol (IP, Internet Protocol) address acquisition method, server and system. Background technique [0002] Such as figure 1 As shown, the existing DNS (Domain Name System, Domain Name System) of the local public network is usually a cluster, and a DNS entry address usually corresponds to several DNS exit addresses. The user configures the entry of the local DNS. During the domain name resolution process, A domain name usually corresponds to several IP addresses. When a user surfs the Internet, he usually enters the domain name in the browser, and the browser first queries the DNS server for the A record of the domain name (that is, queries the IP address), and then communicates with the IP address. The DNS query uses the UDP protocol, and the recursive DNS request to the CDN (Conte...
