Topology (CAIDA AS Rank)

The network's position in the inter-domain routing hierarchy: its customer cone, connectivity, and transit role.

Customer cone

ASes reachable as customers

AS rank

#5,435

by customer-cone size (1 = largest)

Connectivity

1 providers · 0 peers · 3 customers

Transit role

CAIDA transit classification

Upstream providers

Settlement-free peers

Downstream customers

Peering & transit neighbours (CAIDA)

Inferred AS-level relationships: 1 upstream providers, 0 peers and 3 downstream customers. The graph shows the largest few of each; the lists link through.

Relationships are inferred from BGP by CAIDA and refreshed monthly. Transit links are well captured; some private and IXP peering is under-observed, so peer counts are a lower bound.
