M/B/T summary values are rounded; detail tables and exports retain exact totals. Snapshots may have different source dates; transfers can temporarily appear in both registries. Registry holders are not deduplicated corporate groups across RIRs. Names are enrichment; unnamed holders remain in all totals.
External name mapping: The CAIDA UCSD AS to Organization Mapping Dataset, 2026-11. CAIDA organisation names are inferred. Names are joined through registered ASNs sharing a delegated holder ID; routing origins do not determine holdings.
Countries follow the registry’s delegated country code. This is a registration association, not IP geolocation. The original RIPE LIR view instead uses the country prefix in each LIR identifier.
Allocated and assigned records from each RIR’s extended statistics. Public bulk files add names, registration status, network labels and related ASNs. Parent allocations and customer assignments are not added together. These are registered resources, not a measurement of routed or active addresses.
A registry holder ID, kept distinct even when names match. IDs may change between snapshots; company ownership across IDs or RIRs is not inferred. Organisation names, ASN labels and network descriptions are distinguished. Unnamed holders remain visible. APNIC NIR coverage and LACNIC name coverage are incomplete.
