NRO allocation data

Selected local snapshot coverage; not the whole Internet. BGP snapshots: ris-rrc00 11 Oct 08:00 UTC; routeviews2 11 Oct 08:00 UTC; routeviews6 11 Oct 08:00 UTC. Validator: 11 Oct 09:23 UTC. Publication-point issues: 89

Address space details

Overlapping originated prefixes counted once. IPv4 addresses: 66,048

IPv6 addresses: 0

Observed originated prefixes

These are observed BGP origins, not an inventory of registered allocations or transit reachability.

Advanced filters

0 matching prefix–origin pairs. Each pair appears once; source observations are in Details.

No matching route was observed in the available dataset.

Export observed prefixes: TXT · CSV · JSON

AS connectivity

2 unique neighbors in the selected local snapshots. This is the available collector dataset, not a complete map of the Internet. Adjacency does not establish upstream service or peering.

AS hops, not router hops

Darker nodes = larger inferred customer cone. CAIDA IPv4 customer cone (includes the AS itself); unknown / IPv6 cone is gray.
Arrow = provider → customer, not traffic direction. Purple: provider/customer · teal: peer · gray: unknown/mixed. Solid: observed BGP adjacency · dashed: inferred only. A graph path is not an observed BGP route or a promise of transit.

Allocation statistics

NRO/RIR delegated-extended records describe allocation or assignment ranges. They do not prove a BGP announcement or replace more-specific RDAP registration information. Country is the allocation record’s registration country, not the physical location of every address.

NRO data and format

Prefix count history

Uses the public RIPEstat Data API when requested.

Local observation changes

Only comparable successful snapshots are compared. First imports, changed peer coverage and collection gaps are baselines, not new global routes or withdrawals. RPKI transition history is not available before it has been recorded.

No retained changes are available for this resource.

Retained local prefix-count observations

Separate collector series. Missing rows are not zero. Peer-set changes are separate coverage, not a continuous trend.
