Observed originated prefixes

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

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

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.

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.
