Every country's allocated and assigned IPv4 space, collapsed into the smallest possible list of CIDR blocks, one file per country. The lists come from the five Regional Internet Registries' own delegated-extended statistics, generated 2026-10-16. Registry allocation data — where address blocks were handed out — not who is using an address today. IPv4 only. A block allocated to a country may be routed elsewhere, and an address in use in a country may sit in a block allocated to another one. For who is announcing a prefix now, the network and country pages use live data; these files are the paper trail underneath them.
RIR delegated-extended statistics: AFRINIC, APNIC, ARIN, LACNIC and RIPE NCC (allocated and assigned IPv4 records only). IPv4 only. Totals:
239 countries,
178,975 prefixes,
3,687,618,208 addresses. Generated by
tools/gen-country-prefixes.py.

Each RIR publishes a delegated-<registry>-extended file with one
line per delegation: country, start, address count, date and status. The generator
reads the IPv4 lines with status allocated or assigned
(space that merely exists is not a country's), turns each delegation into the CIDRs
that cover it, and then merges every country's blocks so overlapping and adjacent
prefixes collapse into the shortest correct list — a pair of neighbouring /24s
becomes one /23. The address totals therefore match the registries' own
allocated-plus-assigned figure rather than adding up per record.
Attribution: prefix data © the five RIRs (AFRINIC, APNIC, ARIN, LACNIC and RIPE NCC), from their delegated-extended statistics. Geolocation elsewhere on this site is the DB-IP City Lite database, licensed CC BY 4.0. Registry allocation data only; no inference about who uses an address today is made here.
IPv4 Land Grab asks you to place a whole /8 on the map of holders, and Higher or Lower turns two countries' prefix and address counts into a two-second question. The tools index has the rest.
