AS28580 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 AS28580

3 upstreams

AS3356 AS28649 AS37468

AS28580 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS28580 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS28580

7 downstreams

AS52887 AS61855 AS266140 AS266462 AS267976 AS268989 AS273335

AS28580 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.
