Observed originated prefixes

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

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

Observed AS neighbors

1 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.

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

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.
