It is important to note that Art-Net is specifically designed to be used in a closed network situation only. Art-Net is not designed to be used in conjunction with the Internet. On top of that, it is not a good idea to run Art-Net over a building’s internal network. Your lighting rig (or architectural installation) should run on its own isolated network. This, again, will help to make sure that there are fewer opportunities for your Art-Net network to have problems. So, keep your lighting network separate from your collection of YouTube videos of dancing. Cute they may be, your lights don’t care.
