The invention discloses a method, device and system of a domain name server (DNS) for buffering updating. The method and device and system of the DNS for buffering updating comprise main contents as following: Regarding to any of echo reply message reserved in the DNS, effective buffering time which is corresponding to the echo reply message is confirmed when the echo reply message starts to be buffered. Time duration that the echo reply message is currently reserved in the DNS is confirmed, when the difference between the effective buffering time and the time duration is greater than zero and less than a preset updating duration, and a process that the echo reply message is updated is carried out. Due to the fact that echo reply message buffering is updated before expiration, the problems that due to the fact that the echo reply message buffering is not updated because of the expiration and a large number of domain name queries have a request to get to a back-end DNS to carry out recurrent iteration queries, the DNS system has a low-speed response to the request of the domain name queries and response delay is larger are effectively avoided.
