Suggestion of JP Zone Authoritative DNS Server Locations by Country Analysis of Query IP Address

IP anycast is a technology that assigns a common IP address to multiple devices on the Internet. With the recent development of the Internet, the use of anycast technology in the operation of authoritative DNS servers is crucial to ensure stability, reliability, and accessibility. The main objective of IP anycast is to reduce response time for DNS queries. However, in the multisite deployment of anycast, there are many cases where the traffic distribution anticipated for fast query response is not achieved even after the installation of new sites. This paper focuses on the number of hops of DNS queries and makes suggestions to encourage domestic processing of DNS queries sent from within the country for a fast response time. As a result, the domestic consumption rate in the Netherlands is below 70% and the network has room for improvement. And adding a node for JP zone authoritative DNS server in Ireland, where there are many queries to the German and UK nodes, would improve the effectiveness of anycasting.
