regional internet registry (RIR)

One of five bodies delegating IP address space and AS numbers per world region; their databases are the authoritative source for allocations, and most infrastructure datasets normalize coverage by RIR.

In this catalog it appears concretely: - RIPE Database — "RIPE NCC service region: Europe, the Middle East, and parts of Central Asia (75 member countries)". - RIPEstat Data API — "RIR-specific views for all five Regional Internet Registries". - Spamhaus DROP Lists — "Global - netblocks and ASNs from all five RIRs".

Conventions decide whether two sources join; ignore them and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.

The failure mode is concrete: a source can carry the regional internet registry (RIR) label while differing from what you need on exactly the dimension that matters — RIPE NCC service region: Europe, the Middle East, and parts of Central Asia (75 member countries). Comparing two sources on that line usually settles the choice faster than any feature matrix.

82.4% of the 1,744 cataloged datasets are free to access, and RIPE Database lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open RIPE Database and confirm its record — "RIPE NCC service region: Europe, the Middle East, and parts of Central Asia (75 member countries)" — against the files you actually receive. 2. Open RIPEstat Data API and confirm its record — "RIR-specific views for all five Regional Internet Registries" — against the files you actually receive. 3. Open Spamhaus DROP Lists and confirm its record — "Global - netblocks and ASNs from all five RIRs" — against the files you actually receive. 4. Pin down update cadence in writing. Across this catalog, 22.6% of 1,744 datasets refresh daily and 64 still arrive only through a manual request form, so ask exactly how fresh each release is. 5.
