Topology (CAIDA AS Rank)

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

Customer cone

edge network — no downstream ASes

AS rank

#22,450

by customer-cone size (1 = largest)

Connectivity

3 providers · 1 peers · 0 customers

Transit role

Enterprise / stub

edge network, buys transit only

Upstream providers

Settlement-free peers

Downstream customers

Peering & transit neighbours (CAIDA)

Inferred AS-level relationships: 3 upstream providers, 1 peers and 0 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

AS1000 PISL-24-1000 - CORIX NETWORKS

Downstream customers0

buy transit from it

None recorded.

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.
