Moving ahead we are looking at expanding the universe.. in ipv6, the organisations ipv6 multicase address's are ffx8::/16 which is just a miserable 112 bits for usable multicast address's. ( this assumes we mirror the design of ipv4 sACN ). That gives us just 2^112 or ~ 5.2E33 universes. Thats ~8.9E33 pixels A Galaxy S6, has the highest pixel desnity of all cell phones at 22.7 pixels/mm, but for this discussion lets round up to 30pix/mm. This would be 300 times the pixel density of the video panels used at eurovision this year. thats 30 x 1000 x 1000 = 30,000,000 pixels/km or 9e14 pixels / square km The surface area of all 8 planets and the sun is 6.22e+12/km2. That gives us enough pixels to cover them 159,297,963 times. Should be just enough.
