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

#3,186

by customer-cone size (1 = largest)

Connectivity

4 providers · 1 peers · 7 customers

Transit role

Transit / access

carries traffic for downstream customers

Upstream providers

Settlement-free peers

Downstream customers

Peering & transit neighbours (CAIDA)

Inferred AS-level relationships: 4 upstream providers, 1 peers and 7 downstream customers. The graph shows the largest few of each; the lists link through.

Upstream providers4

Settlement-free peers1

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.
