Scope: Not Disclosed

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

#6,579

by customer-cone size (1 = largest)

Connectivity

2 providers · 4 peers · 2 customers

Transit role

CAIDA transit classification

Upstream providers

Settlement-free peers

Peering & transit neighbours (CAIDA)

Inferred AS-level relationships: 2 upstream providers, 4 peers and 2 downstream customers. The graph shows the largest few of each; the lists link through.

Upstream providers2

give this network transit

Settlement-free peers4

exchange traffic directly

Downstream customers2

buy transit from it

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.
