The IP addresses to scan can be specified in any format that Nmap understands, including the network-prefix notation (`192.168.1.1/24`) and the range notation (`192.168.1.1-255`). +

+ Please keep in mind that modern smart phones will usually turn off WiFi when they are idle. Simple trackers like this may not be reliable on their own. +

+ You might have to install the packages for `arp` and `nmap`. On Debian based hosts (for example Hassbian and Raspbian) do so by running `$ sudo apt-get install net-tools nmap`. On a Fedora host run `$ sudo dnf -y install nmap`.
