Philips HUE

So how do you discover the IP of your device. On linux the answer is arp-scan (if it's not on your system apt-get install it):

Using arp-scan --interface=wlan0 I got:

192.168.*.** *************** (Unknown)
192.168.*.11 00:17:88:20:e8:6e Philips Lighting BV
192.168.*.** *************** (Unknown)

So now I know my IP.
