AS13037 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 AS13037

4 upstreams

AS1299 AS2914 AS6461 AS215638

AS13037 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS13037 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS13037

3 downstreams

AS44697 AS51766 AS208697

AS13037 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.
