Using the devices-list import feature

You may import a group of hosts for the purposes of ping, WoL etc.
Generate a plain text file with each device on a separate line in the following format:

IP Number||MAC address||My Remote Host 1
IP Number||MAC address||My Remote Host 2
IP Number||MAC address||My Remote Host 3

NB: all components are separated by two pipe chars ||

If you do not know or need to reference the MAC address field, you may leave it blank, but keep the surrounding separators. In such a case, a valid entry might look like this: 10.1.3.37||||remote server
