摘要

A method, a system, an intelligent DNS, a computer program and a storage medium for parsing DNS parsing requests are provided. The method according to an embodiment comprises: an intranet DNS and an intelligent DNS are provided, and each stores the records indicating the relationship of URLs and IP addresses separately; when the record corresponding to the URL in the DNS parsing request is not found in the intranet DNS and intelligent DNS, the intelligent DNS queries an internet DNS; the intelligent DNS receives a feedback response packet from the internet DNS, and determines whether the business address of local network is comprised in the response packet; according to the result of the determination, IP addresses in the response packet are reordered or the response packet is sent to the intranet DNS directly. According to the scheme provided in the invention, when a Cache system and an intelligent system coexist, a user can access to IDC resources firstly, which optimizes the user access.
