RaspBerry Pi Command Line/Application - List IP Devices

I'm trying to make a very simple Raspberry Pi application that would auto-update with all the IP addresses, Mac addresses, and their respective device names that are all on the same network. I have absolutely no idea where to start, any recommendations on how to get this done?

I play to connect a LCD and mount it next to my router so I have easy access to all the devices that are connected to my network.

Thanks for the help!

How about "arp-scan" command?

$ sudo apt-get install arp-scan
$ sudo arp-scan -l --interface wlan0
Interface: wlan0, datalink type: EN10MB (Ethernet)
Starting arp-scan 1.8.1 with 256 hosts (http://www.nta-monitor.com/tools/arp-scan/)

Your interface might be eth0 instead of wlan0.

(Added) Because the arp-scan package contains an old vendor list file, many devices fail to get their name (represented as "(Unknown)"). To correct that:

$ git clone https://github.com/royhills/arp-scan.git
$ sudo cp /usr/share/arp-scan/ieee-oui.txt{,.org}
$ sudo cp arp-scan/ieee-oui.txt /usr/share/arp-scan/

After refreshing the file, we can get the output like the following:

$ sudo arp-scan -l --interface wlan0
Interface: wlan0, datalink type: EN10MB (Ethernet)

All devices correctly got their (vendor) name.
