How to Replace Digital Certificates for Wi-Fi
In the student dormitory, IP addresses cannot be allocated in a static manner.
As far as concerned, there is no restriction to this kind of usage. However, if everyone starts doing the same thing, the student dormitory connection will collapse as a whole. Since all rooms share a common IP address, please try to use it moderately. In cases where excessive use is noticeable (as judged by the Research Center for Advanced Computing Infrastructure), we will suspend or limit the connection.
