This page gives the
lists of IPv4 addresses and IPv6 addresses delegated in each country of the world by Regional Internet Registries (RIRs) as
text files, according to RIRs delegations files:
AFRINIC (Africa),
APNIC (Asia-Pacific),
ARIN (North America),
LACNIC (Latin America and the Caribbean) and
RIPE NCC (Europe, the Middle East and parts of Central Asia).
The format of IPv4 delegations is
Address/Prefix for most delegations and
First address-Last address for some delegations:
- Most IPv4 delegations correspond to a single /Prefix address range. They appear as Address/Prefix.
- Some IPv4 delegations correspond to several consecutive /Prefix ranges with the same holder, aggregated together in a single delegation (for example a /23 and the following /24 aggregated in a delegation with 768 addresses). They appear as First address-Last address.
The format of IPv6 delegations is
Address/Prefix.
