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

#3,917

by customer-cone size (1 = largest)

Connectivity

3 providers · 1 peers · 5 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: 3 upstream providers, 1 peers and 5 downstream customers. The graph shows the largest few of each; the lists link through.

Upstream providers3

give this network transit

Settlement-free peers1

exchange traffic directly

AS293 ESNET - ESnet

Downstream customers5

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.
