Subdomain DNS Record Management System

Subdomain managers and administrators can register and change subdomain records for the domain they are responsible for from the subdomain management system.

Caution

  • This procedure applies only to domains whose on-campus DNS subdomains are managed by the university-wide DNS server.

  • If you are using a virtual domain server or a department-specific DNS server as your DNS server, you cannot update using this method.

  • If you would like to manage your own campus DNS subdomains on the campus-wide DNS server, please contact support@cc.uec.ac.jp

Login

Access the subdomain DNS record management system (on-campus only) and log in with the UEC account of the subdomain manager or subdomain administrator. You cannot log in with any UEC account other than these.

Hint

  • Please use L2TP VPN when accessing from off-campus

  • If you are unable to log in with the subdomain manager’s or subdomain administrator’s UEC account, please contact support@cc.uec.ac.jp to confirm registration.
