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 AS823

2 upstreams

AS819 AS13335

AS823 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS823 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS823

0 downstreams

AS823 has no downstreams recorded.

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.
