Embodiment 1

[0035] According to the embodiment of the present application, an embodiment of a method for detecting an egress IP address is also provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0036] In addition, it should be noted that the method for detecting egress IP addresses provided in this application can be applied to people's daily access to the network. For example, when user A of China Unicom in Heilongjiang initiates a request to visit www.abc.com, the local caching domain name system (ie Cache DNS) server of China Unicom Heilongjiang detects that there is no record corresponding to the domain name www.abc.com. At this time, Cache DNS server to the local domain name...

Embodiment 2

[0071] According to an embodiment of the present invention, an embodiment of a method for detecting an egress IP address is also provided, wherein, image 3 A flow chart showing a method for detecting an egress IP address, consisting of image 3 It can be seen that the method for detecting the egress IP address specifically includes the following steps:

[0072] Step S302, receiving a domain name resolution request from the terminal, wherein the domain name resolution request includes a preset label, and the preset label is used to trigger the authoritative domain name system server to return the egress IP address of the terminal's local domain name system server.

[0073] It should be noted that the local caching domain name system server, that is, the Cache DNS server can receive the domain name resolution request from the terminal, and send the domain name resolution request to the local domain name system server, that is, the local DNS server. Wherein, the termina...

Embodiment 3

[0093] According to an embodiment of the present invention, an embodiment of a method for detecting an egress IP address is also provided, wherein, Figure 4 A flow chart showing a method for detecting an egress IP address, consisting of Figure 4 It can be seen that the method for detecting the egress IP address specifically includes the following steps:

[0094] Step S402, sending a domain name resolution request to the terminal's local caching domain name system server, wherein the domain name resolution request contains a preset label, and the preset label is used to trigger the authoritative domain name system server to return the egress IP address of the terminal's local domain name system server.

[0095] It should be noted that the terminal can send a domain name resolution request to the local caching domain name system server, wherein the terminal can access network devices, such as mobile phones, tablets, and laptops. In addition, the terminal and the local...

Abstract

The invention discloses a method, device and system for detecting an exit IP address. The method comprises the steps of receiving a domain name resolution request sent by a local domain name system server of a terminal, wherein the domain name resolution request comprises a preset label, and the preset label is used for triggering an authoritative domain name system server to return to an exit IPaddress of the local domain name system server of the terminal; obtaining an exit IP address from the domain name resolution request, and packaging the exit IP address in a domain name resolution response; and returning a domain name resolution response to the local domain name system server. According to the invention, the technical problem of scheduling errors of the content delivery network caused by incorrect setting of the exit IP address of the local domain name system server is solved.

Description

technical field [0001] The invention relates to the field of information communication, in particular to a method, device and system for detecting egress IP addresses. Background technique [0002] With the wide application of information and communication technology in people's daily life, people's life, work and study are inseparable from the network. Among them, CDN (Content Delivery Network, that is, content distribution network) is a new type of network content service system, which is built on the basis of IP network, and provides content distribution and service based on the efficiency requirements, quality requirements and content order of content access and application. . However, in the process of people accessing the network, sometimes it is found that the network quality is relatively poor. In addition to the above problems caused by the large number of visits to the server during the current time period, it is also possible that during the CDN scheduling proce...
