This is a visual representation of the Internet’s in-use global unicast IPv6 address space, as seen by the University of Oregon Route Views project on January 1st, 2019. The map is divided into 16,777,216 pixels, each pixel representing 16 ISP-level /32 allocations. A /32 contains approximately 4.3 billion standard /64 networks, and a /64 contains approximately 18 quintillion IP addresses. Each contiguous block represents an announcement in the global BGP address table. The address space is presented as a Hilbert curve, a fractal representation ensuring all blocks appear as squares or rectangles. Colors represent the smallest announcement within that pixel, from /12 to /64. The space depicted is 2000::/4; 3000::/4 is currently allocated but not in use, and 11 more /4s may be allocated to meet future demand.
