AS21430 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 AS21430

4 upstreams

AS1299 AS3491 AS39392 AS47200

AS21430 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS21430 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS21430

7 downstreams

AS15614 AS33943 AS39761 AS42189 AS48451 AS203376 AS209369

AS21430 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.
