Abstract

The invention discloses a DNS domain name obtaining system and method. The system comprises a DNS request packet sending subsystem, a DNS management subsystem and a DNS response packet receiving and analysis subsystem. The DNS request packet sending subsystem, the DNS management subsystem and the DNS response packet receiving and analysis subsystem carry out multithread parallel working. The DNS request packet sending subsystem is used for sending and resending DNS request data packets. The DNS response packet receiving and analysis subsystem is used for receiving DNS response packets and judging whether the DNS response packets are the response packets corresponding to the DNS request packets or not. The DNS management subsystem is used for managing a state value of domain name resolutionservice, carrying out timing after the DNS request data packets are sent, determining the DNS request data packets needing to be resent according to the DNS response packets received by the DNS response packet receiving and analysis subsystem, and triggering the DNS request packet sending subsystem to resend the DNS request data packets needing to be resent, when the timing is carried out to settime. The DNS domain name obtaining system and method provided by the invention are characterized by efficiency and accuracy.

Description

technical field

[0001] The invention relates to the field of DNS domain name acquisition, in particular to a DNS domain name acquisition system and method. Background technique

[0002] The fastest way to obtain a large amount of domain name data information in a short period of time is to go to the server administrator to copy it, and secondly, to obtain domain name data information through real-time monitoring of the domain name server port. These two methods will undoubtedly be the fastest and easiest However, since there are a large number of domain name resolution requests on the Internet every day, the above two methods are also difficult to efficiently complete.

[0003] As for the method of obtaining domain name data information by monitoring the domain name server port in real time, existing solutions can be roughly divided into two categories: synchronous and asynchronous. Synchronous scheme, the acquisition of data is accurate, but the efficiency is very slow. On...
