Anchored Registry · coverage
Why only one registry has pages here
A sponsoring LIR is a relationship the registry records. Exactly one of the five regional registries publishes it. That is not a gap in this directory — it is what the registries do and do not put in their databases, and it is checkable in an afternoon from their own files.
| Registry | Region | Publishes the sponsor? | Pages here |
|---|---|---|---|
| RIPE NCC | Europe, the Middle East and Central Asia | yes | 33,867 |
| APNIC | Asia and the Pacific | no | — |
| ARIN | North America | no | — |
| LACNIC | Latin America and the Caribbean | no | — |
| AFRINIC | Africa | no | — |
What was actually checked
- RIPE NCC publishes a sponsoring-org attribute on independent resources. 33,867 of them name a third-party sponsor, under 3,026 organisations.
- AFRINIC publishes its whole database openly. It contains the attribute zero times.
- LACNIC publishes its database too. Zero occurrences, and its schema is little more than the range, the country and the status.
- APNIC requires credentials for its bulk dumps — they answer 401 — so nothing beyond the delegation statistics can be read.
- ARIN publishes no bulk whois. Its model has End Users registering directly, so there is no sponsoring relationship to record in the first place.
What is global anyway
All five registries publish delegation statistics. Merged, they say which registry holds any number on the internet — 17,310 ranges covering 2,612 AS-number bands, 14,672 IPv4 and 26 IPv6. So the search answers for a resource in any region: it will tell you whose registry it is in, and that the registry does not publish who sponsors it, rather than pretending not to know.
