Peers of AS25500

3 peers

AS6939 AS48919 AS49544

AS25500 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 AS25500

2 upstreams

AS3326 AS12687

AS25500 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS25500 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS25500

1 downstreams

AS20660

AS25500 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.
