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 AS5974

1 upstreams

AS27064

AS5974 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS5974 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS5974
