Peers of AS15372

6 peers

AS680 AS6939 AS8218 AS24961 AS39351 AS24482

AS15372 peers with these other Autonomous Systems.

Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.

Upstreams of AS15372

5 upstreams

AS174 AS3320 AS9136 AS13237 AS21413

AS15372 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS15372 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS15372

4 downstreams

AS11528 AS203592 AS208508 AS215556

AS15372 provides internet connectivity to these downstream Autonomous Systems.

A downstream is a customer Autonomous System that pays another AS (its provider) for internet access. The provider AS carries the downstream's traffic and makes its network reachable.
