Abstract

The invention discloses a method and a system for distinguishing DNS users. The method for distinguishing DNS users comprises the steps that: a cloud DNS server assigns identity identification codes to all DNS user terminals; one DNS user terminal transmits a request packet to the outside by means of an intranet DNS server, and the intranet DNS server adds an identification question into the request packet, wherein the identification question comprises the identity identification code; and the cloud DNS server receives the request packet, and determines the DNS user terminal transmitting the request packet according to the identification question in the request packet. The system for distinguishing DNS users comprises the cloud DNS server, the intranet DNS server and the DNS user terminals.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and system for distinguishing DNS users. Background technique [0002] With the development of cloud technology, cloud domain name service (Domain Name Service, DNS) is more and more widely used. The cloud DNS service provides public or private DNS additional functions. The most typical additional function is security monitoring. For example, the cloud DNS service can detect whether the DNS request is a dangerous domain name, whether someone maliciously uses DNS as a tunnel, and whether someone visits a malicious website. At the same time, the cloud DNS service can respond and process according to the detection results, for example, it can block the request, not return the result, or issue a warning. However, different response processing based on the detection results needs to be judged according to different users. However, the existing DNS service itself cannot ...
