What is the DHCP address range and how can I reserve an IP address for a device?
The default DHCP server assigns IP addresses from 192.168.0.100 to 192.168.0.199 with a lease time of 120 minutes. To reserve a static IP for a device, go to DHCP > Address Reservation, click Add New, enter the device's MAC address and the desired IP address, then save.
