AS28209 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 AS28209

3 upstreams

AS3356 AS22381 AS264409

AS28209 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS28209 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS28209

3 downstreams

AS26615 AS28138 AS265380

AS28209 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.
