Who sponsors the RIPE region
17,145 AS numbers and 17,007 address blocks are held by an End User and sponsored by a Local Internet Registry. 3,040 organisations do that sponsoring. Counted from RIPE’s published database dumps — you can count it yourself from the same files.
Worth knowing before anybody tells you they are a big LIR: the region has 20,715 organisations registered as LIRs, and only these 3,040 sponsor a single third-party resource. The median sponsor holds 3. 3 hold more than five hundred.
The shape of it
| Resources held | Sponsors | Share of sponsors | Resources covered | Share of market |
|---|---|---|---|---|
| 1 | 793 | 26% | 793 | 2% |
| 2–3 | 924 | 30% | 2,175 | 6% |
| 4–10 | 784 | 26% | 4,706 | 14% |
| 11–50 | 419 | 14% | 8,973 | 26% |
| 51–200 | 97 | 3% | 8,703 | 25% |
| 201 and more | 23 | 1% | 8,802 | 26% |
The largest single sponsor holds 984 — 2.9% of the region’s sponsored resources. So this is a fragmented market rather than a won one, and size is not what distinguishes one sponsor here from another.
The 200 largest of 3,040. The tail is long: most sponsor one or two resources, which is worth knowing when somebody tells you they are a big LIR.
