IP addresses by country

Every public IP address is allocated to an organisation, and every organisation is registered in a country. Aggregating those records gives a picture of how the address space is actually distributed — which is far less even than the map of internet users.

How allocation works

IANA hands large blocks to five regional internet registries, each responsible for a part of the world:

Registry	Region
ARIN	United States, Canada, parts of the Caribbean
RIPE NCC	Europe, Middle East, Central Asia
APNIC	Asia-Pacific
LACNIC	Latin America and the Caribbean
AFRINIC	Africa

Each registry assigns from its pool to member networks and publishes, daily, exactly which blocks went where. Those files are the basis of every country page here.

Why the distribution looks unfair

IPv4 allocation tracks history rather than population. Networks that connected early received blocks under far looser rules, and nobody took them back. The result is that a handful of early-adopting countries hold a share of IPv4 wildly out of proportion to the number of people living in them, while large, late-connecting populations run on carrier-grade NAT.

IPv6 has no such constraint, which is why adoption is highest precisely where IPv4 was scarcest.

Each country page below shows its IPv4 and IPv6 allocations, its registry, its largest networks by address count, and current IPv6 adoption.
