TL;DR: In this paper, the authors propose a dynamic update request mechanism to reduce a processing burden and accelerate a processing speed when updating domain information stored in a DNS server system. But the dynamic updating mechanism requires the primary DNS server to update zone data stored in the database while reflecting the data with the accepted dynamic update requests.
Abstract: PROBLEM TO BE SOLVED: To reduce a processing burden and to accelerate a processing speed when updating domain information stored in a DNS server system. SOLUTION: When dynamic update request information requesting the dynamic updating of zone data is received from a DNS dynamic update client device 3, a primary DNS server system device 1 updates zone data stored in a database 14 while reflecting the data with the accepted dynamic update request information and stores the dynamic updating information in a dynamic updating information table stored in a memory journal 16. The primary DNS server system device reads and acquires from the memory journal information relating to the dynamically updated zone data requested by a differential zone transfer request telegraph, creates a differential zone transfer response telegraph using such information relating to the zone data and transmits the created telegraph to a secondary DNS server system device 2.
