The image is a Hilbert curve map of the IPv4 address space, with each pixel (block when zoomed in) representing an IP address. See https://xkcd.com/195/ https://xkcd.com/195/ The colour of pixel represents the domain name. The R,G and B components are resolved based on the TLD - so my.company.com and bob.company.com have the same G and B components but a different shade of red. For example, the light purple of the 52.x.y.z block all resolve to AWS Compute domains. On the left middle of the image much of the 34.x.y.z block resolve to googleusercontent.
