IPv6 enabled Christmas Tree
Ping it to light it up!
2001:6a8:2880:2018::AA:BB:CC for HTML Color #AABBCC
2001:6a8:2880:2018::FF:00:00 for color RED
2001:6a8:2880:2018::00:FF:00 for color GREEN
2001:6a8:2880:2018::00:00:FF for color BLUE
2001:6a8:2880:2018::FF:FF:FF for color WHITE
... and so on...
Every ping packet flashes a random LED in the requested color.
Keep in mind there is a few seconds streaming delay on youtube
You won't get a ping reply (saves me bandwidth) but in the livestream you should see LEDs flashing for every packet received.
Update 2017-12-19:
The IPv6 Christmas Tree is back!
Since I received lots of messages asking me when the tree would come online this year, I decided to give it another go.
The tree has more bandwidth this year (1Gbit/s) so ping away!
