AS39521 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 AS39521

6 upstreams

AS174 AS5511 AS6206 AS6830 AS6939 AS61138

AS39521 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS39521 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS39521

6 downstreams

AS31800 AS47690 AS60117 AS61060 AS207778 AS213784

AS39521 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.
