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 AS23600

4 upstreams

AS4766 AS8763 AS9318 AS9858

AS23600 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS23600 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS23600

2 downstreams

AS14650 AS24151

AS23600 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.
