Public DNS Resolver

Japanese public DNS resolvers are open services that turn domain names like example.jp into IP addresses. They are recursive resolvers that look up records on your behalf, not the authoritative nameservers that publish records for a domain. Operated by Japanese infrastructure providers, hosting companies, and research networks, they are open to anyone regardless of Internet provider.

This category covers resolvers running on infrastructure inside Japan, which can shorten the round trip for domestic users compared with overseas alternatives.

DNS over TLS (DoT) wraps DNS queries in a TLS-encrypted channel on port 853 and is usually turned on at the operating system or router level.

DNS over HTTPS (DoH) sends DNS queries over HTTPS on port 443, so they look like ordinary web traffic and can be enabled directly from modern browsers.
