#195: Map of the Internet explain
Map of the Internet The IPv4 Space, 2006 This chart shows the IP address space on a plane using a fractal mapping which preserves grouping–any consecutive string of IPs will translate to a single, compact, contiguous region on the map. Each of the 256 numbered blocks represents one 8 subnet (containing all IPs that start with that number). The upper left section shows the blocks sold directly to corporations and goverments in the 1990’s before the RIRs took over allocation.
