Observed originated prefixes
These are observed BGP origins, not an inventory of registered allocations or transit reachability.
14 matching prefix–origin pairs. Each pair appears once; source observations are in Details.

AS connectivity
191 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.

Sources & methodology
Inferred topology and tier estimates do not establish commercial agreements. AS hops count AS relationships, not routers or observed traffic paths. Arrows run from provider to customer; peer links have no arrows. Cross-links connect other included networks. IPv4 relationships guide the All layout; IPv6 differences remain in connection details. Cyclic relationships are marked separately. Size uses the global, logarithmic IPv4 CAIDA customer cone including the AS itself; IPv6 size data is unavailable.

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.
