Peers of AS9644

0 peers

AS9644 has no peers recorded.

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 AS9644

1 upstreams

AS9318

AS9644 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS9644 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS9644

2 downstreams

AS17592 AS23743

AS9644 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.
