The following DNS services are provided for the campus network. If the static address is needed, please set the address shown below. Also, if there are no special circumstances, please specify ns1, which enables DNS Firewall feature*.

* DNS Firewall is a security feature that prevents accessing to dangerous websites such as phishing, fake, and malicious websites. It works at domain name resolution stage (e.g. www.example.jp -> 192.0.1.3).

The DNS servers (150.65.1.1 and 150.65.3.6) used before 2017 were permanently shut down on May 17, 2025.
If your device (especially those with static IP addresses) cannot connect to the network after this date,
please check and update your DNS server settings.
