Peers of AS58542

0 peers

AS58542 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 AS58542

1 upstreams

AS4134

AS58542 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS58542 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS58542

3 downstreams

AS45090 AS59019 AS137718

AS58542 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.
