Public DNS Resolver
Public DNS Resolvers are open-access services that translate domain names (like example.jp) into IP addresses. Unlike DNS servers provided by your ISP, public resolvers are available to anyone and are typically operated by Japanese infrastructure providers, hosting companies, or research networks.
This category includes only resolvers that are operated by Japanese organizations, hosted within Japan, and accessible to all users regardless of ISP.
Some resolvers support encrypted DNS protocols that enhance privacy and security:
- DoTDNS over TLS (DoT) encrypts DNS queries using the TLS protocol. It runs on port 853 and is typically configured at the system or router level.
- DoHDNS over HTTPS (DoH) sends DNS queries over HTTPS (port 443), making them indistinguishable from regular web traffic. This increases the chance of bypassing restrictive firewalls and is widely supported by modern browsers and operating systems.
Using a Japanese public DNS resolver may improve DNS response times depending on your environment and can also help reduce the risk of filtering or surveillance at the ISP level.
