A very interesting map of the IPv4 address space

This is a very interesting map of the IPv4 address space. Following image shows a visualization of BGP routing data taken from the Routeviews project. Here, 1-dimensional IPv4 address space is mapped into a 2-dimensional image using a 12th order This means that CIDR netblocks always appear as squares or rectangles in the image.

Each pixel in the original 4096 x 4096 image represents a single /24 network containing up to 256 hosts. The pixel color shows the size of the route advertisement covering that space ranging from /8 (purple) to /32 (red). Black represents space without a route and grey indicates reserved space.

You can order this map as a full size poster from project home page. I'm going to ask some one to get this cool map in our data center monitoring facility Note that most large corporations and government holds large IPv4 address space. I guess with the IPv6 we don't have to worry about allocation problem as it is a much larger address space that allows greater flexibility in assigning addresses.
