The Known Hosts Configuration feature allows you to map a name (printer, scanner, laptop, etc.) to the IP address of a device on the network. This assigns a new hostname that can be used to conveniently identify a device within the network, such as an office printer.
Click Add to name a device in your network.
Fill in the following fields.
Hostname: Choose a name that is meaningful to you. No spaces are allowed in this field.
IP Version: The IP version of the host.
IP address: The address of the device within your network.
EXAMPLE: a personal laptop with IP address 192.168.0.164 could be assigned the name “MyLaptop”.
Since the assigned name is mapped to an IP address, the device’s IP address should not change. To ensure that the device keeps the same IP address, go to Network Settings → DHCP Server and reserve the IP address for the device by selecting the device in the Active Leases list and clicking “Reserve”.
