Peers of AS5387

3 peers

AS3267 AS25091 AS49673

AS5387 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 AS5387

4 upstreams

AS9049 AS15493 AS31200 AS42451

AS5387 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS5387 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS5387

2 downstreams

AS30797 AS208903

AS5387 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.
