Peers of AS42908

0 peers

AS42908 has no peers recorded.

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 AS42908

1 upstreams

AS5610

AS42908 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS42908 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS42908

2 downstreams

AS33442 AS202643

AS42908 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.
