Peers of AS14041

7 peers

AS14041 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 AS14041

5 upstreams

AS14041 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS14041 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS14041

24 downstreams

AS14041 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.
