AS42845 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 AS42845

3 upstreams

AS174 AS3257 AS6762

AS42845 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS42845 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS42845

4 downstreams

AS43121 AS47977 AS198978 AS199117

AS42845 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.
