AS9993 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 AS9993

2 upstreams

AS2497 AS4713

AS9993 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS9993 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS9993

3 downstreams

AS24270 AS38654 AS55390

AS9993 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.
