AS47232 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 AS47232

2 upstreams

AS3257 AS39392

AS47232 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS47232 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS47232

55 downstreams

AS47232 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.
