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.

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.
