A new interactive visualization plots every public IPv4 address in existence, offering a stark look at how the internet's foundational addressing system is distributed across the globe. The project, created by a network engineer and data artist, renders each of the roughly 3.7 billion usable IPv4 addresses as a colored dot on a world map.

Mapping the Unmapped

The map draws on regional internet registry data to show which organizations or countries control each block of addresses. Colors indicate allocation status: blue for active, red for reserved, gray for unassigned. The result is a dense, pixelated view of digital real estate.

Large swaths of North America and Europe appear saturated with blue, while vast regions in Africa and parts of Asia remain mostly gray. The visualization makes clear how unevenly the original IP address pool was distributed decades ago.

What the Map Reveals

The United States alone controls more than 1.5 billion IPv4 addresses, roughly 40 percent of the total. China, despite having four times the population, holds fewer than 350 million. Many developing nations have minuscule allocations.

The map also highlights the growing problem of address scarcity. All five regional registries have exhausted their pools of new blocks. Organizations now buy and sell used addresses on secondary markets, with prices reaching $50 per IP.

Why This Matters

For network engineers, cloud architects and IT managers, this visualization underscores the urgency of migrating to IPv6, which offers a virtually unlimited address space. Companies that delay risk facing higher costs for legacy IPv4 addresses or being unable to expand their networks.

For everyday internet users, the map illustrates why some websites load slowly in certain regions or why new services sometimes struggle to get online in underserved areas. The digital divide has a physical foundation in these numbered blocks.

The project is open source, allowing anyone to explore the data or build their own tools for analyzing IP allocation patterns.
