If the studio uses large switches, please install routers in the switches and computers to restrict the network (if there are a large number, you can buy large routers) and set them to dynamic IP or static IP mode. (If the switch supports setting, you can set it directly in the switch. )
Take the TP-LINK router as an example:
1. Log in the background of TP-LINK router.
2. Click IP to bind to the MAC and bind each computer to a fixed intranet IP. (You can check the MAC address through "Network Connection Status")
3. After binding, use the Internet access control function to set the restriction mode. The specific settings depend on the requirements.
