What a PI assignment costs
RIPE charges a member €75 a year for each provider-independent address assignment, on top of €1,800 for the membership — the 2026 Charging Scheme. Everything above that is the sponsor’s own price:
| Sponsoring LIR | PI assignment / year | Their price page |
|---|---|---|
| Bakker IT NL | €135 | check it |
| iFog CH | 99 CHF | check it |
| Snapserv CH | €125 | check it |
| ServPerso BE | quoted | not linked |
| Ipregistry — | €240 | not linked |
Read from each sponsor’s own published price list on 2026-08-22, 4 days ago. iFog publishes in Swiss francs and the figures are its own, not a conversion. Where a row says “not linked”, the price was not re-read against the vendor’s page and should be checked before you rely on it.
Anchored Registry quotes rather than publishing a figure, because an AS number and an address assignment do not cost the same to sponsor and one number for both would overcharge somebody.
