About and API

The pipeline runs every 4 hours. It reads the transfer logs and the extended delegated statistics files of AFRINIC, APNIC, ARIN, LACNIC and RIPE NCC, resolves holders through RDAP and whois (and through the JPNIC and KRNIC whois for national-registry members), and dates past reclaims with RIPEstat allocation history.

Holder lookups do not follow the 4-hour cycle. A background worker queries RDAP when a delegation is new or has changed, and re-checks resources whose registry publishes no organization at growing intervals of up to a month. A registry with nothing queued has no recent lookup run; Data status marks it idle rather than late, and lists the last run and the number of lookups waiting for each registry.

API answers are cached for 5 minutes at the edge and 1 minute in the browser. Edge copies are keyed to the deployment and to the sync that produced the data, so a page trails a new sync by at most about 90 seconds.

Transfer

Registered space that moved from one holder to another under a registry transfer policy, as listed in the RIR transfer logs. Transfers →

Merger or acquisition

Space that changed holder because one organization merged with or acquired another. Registries log these apart from market transfers. Mergers →

Allocation

Space a registry issued from its free pool to a member, usually an ISP or LIR that assigns it onward to its customers. Allocations →

Assignment

Space a registry issued directly to an end user for its own network, not for onward assignment. Assignments →

Reclaim

Space that left its holder and is back in the registry’s free pool: returned, revoked or deregistered. Reclaims →

Deal

Transfer or merger records on the same day between the same two organizations. Registries often list one deal as many ranges, so the site leads with deals and addresses rather than record counts.

Deal size

IPv4 addresses per IPv4 deal. The overview shows the median, with the mean beside it: one deal of several million addresses moves the mean and leaves the median where it is.

Last 12 months

The 365 days up to the export, compared with the 365 days before. Rankings and the largest deals use the same window.

Month to date

The latest month in the monthly charts is still filling; its bar is hatched.

Registry history

Allocations, assignments and reclaims before daily observation began are rebuilt from the registration dates in the delegated files and from RIPEstat. The history stops where daily observation starts, so the two never count the same record.

National registries

APNIC lists members of JPNIC, CNNIC, TWNIC, KRNIC, IDNIC, VNNIC and IRINN as “registry/member”. The site shows the member name with the national registry as a badge.

Countries

Country codes are the registration countries in the registry data, not where a network is used.

Inferred records

Most allocations, assignments and reclaims are not observed events. Before daily observation began, an allocation or assignment is a current delegation dated by the registration date in the delegated file, and a reclaim is the day a delegation ended according to RIPEstat allocation history. The kind pages state how many records of the last 12 months are of this sort. In the last 12 months (since 2025-11-15): 7,860 of 12,121 allocations (65%), 2,363 of 2,884 assignments (82%), 3,877 of 6,007 reclaims (65%).

Handover

History is derived only for days before daily observation of a resource family began, and a record the monitor observed is never rebuilt from history, so no day and no record is counted from both sources. IP ranges: history to 2026-08-04, observed from 2026-08-05; AS numbers: history to 2026-07-26, observed from 2026-07-27.

Reclaims across the handover

History knows a reclaim only while the space is still in a free pool, so it misses space that was returned and reissued since. Daily observation sees every return. A year-on-year change in reclaims that spans the handover is therefore overstated.

Country coverage

Cross-border figures count only transfers whose log names a country on both sides. In the last 12 months, 6,627 of 8,715 transfers (76%) name a country on both sides. Codes such as SC, BZ and VG often mark where a holder is incorporated rather than where the network runs.

Holders without an organization

Some delegations have no organization in their registry’s RDAP or whois: sub-allocations and assignments registered under a maintainer or a person. The site then shows the holder of the covering block and never substitutes a person or a contact for an organization.

National-registry members

For members of JPNIC and KRNIC the member is resolved through the national registry’s whois; members of the other national registries appear under the national registry’s name.
