Embodiment Construction

[0024] see figure 1 , figure 1 It shows a schematic flow chart of establishing an address mapping data set in an embodiment, specifically including steps S11-S14:

[0025] Step S11: establishing an address mapping data set, which is used to store data required by the system, including manufacturer ip address, cname data, and CDN line ip address;

[0026] Step S12: Initiate a cname resolution request to the DNS server with the ip address in the ecs request to obtain the manufacturer's CDN line ip list;

[0027] The IP address conforms to the IPV4 standard. After receiving the ecs request, the DNS will use the IP information to judge the visitor's country, province, city, ISP and other information, and analyze the province corresponding to the cname and the ISP line according to the province corresponding to the IP and the ISP attribution. IP.

[0028] Step S13: Analyzing the response data returned by the DNS server, obtaining the ip list of the manufacturer's CDN line, and s...

Abstract

The invention discloses a domain name resolution method for hiding manufacturer information which comprises a method for establishing an address mapping data set and a method for querying a domain name request, and further discloses a domain name resolution system for hiding the manufacturer information. According to the method and the system provided by the invention, the risk of information leakage of the cache can be obviously reduced by hiding the fused manufacturer cache, the security is improved, the analysis time consumption is reduced, and meanwhile, more data analysis with coverage capability is obtained to provide reference for subsequent further service optimization, and therefore the method has obvious technical advantages and beneficial effects.

Description

technical field [0001] The invention relates to the field of integrated CDN, in particular to a domain name resolution method and system for hiding vendor information. Background technique [0002] When CDNs are integrated, multiple CDNs are usually selected for many reasons, such as mutual backup, introduction of competition, better service quality, or some manufacturers’ CDNs have no resources in certain areas and poor service quality, etc. However, when the intelligent system is used to manage the cnames of each line provided by the manufacturer, the service domain name resolution will find that there are multiple layers of cnames in the domain name resolution, which leads to a long time-consuming resolution and the problem of exposing the manufacturer's cname information during the resolution process. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art, and provide a method for domain name ...
