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 AS25515

1 upstreams

AS12389

AS25515 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS25515 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS25515

3 downstreams

AS8557 AS47335 AS49261
