How can I effectively manage IP addresses on my intranet in a hospital?

You can use Ruijie Network's lightweight access solution. This program uses SDN technology. When a device is accessing the intranet, the SDN management interface will remind the administrator at the first time that a terminal is going to enter the intranet, and at the same time display the MAC address of the device that is going to enter the intranet, the location of the access location, the vendor and other information.
