AS20559 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 AS20559

6 upstreams

AS174 AS8455 AS20562 AS24785 AS39686 AS49685

AS20559 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS20559 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS20559

1 downstreams

AS39390

AS20559 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.
