Pixelflood over IPv6 The Pixelflood protocol over IPv6 uses only the destination address of the IPv6 header to change a pixel. This makes this protocol much more simple than the usual tcp based Pixelflood. It can be used to change pixels on displays of size up to 65536x65536 pixels, which should meet the requirements of the nearest future displays. For color space, the 4 Byte RGBA Color space is used.
