Peers of AS557

1 peers

AS1828

AS557 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 AS557

5 upstreams

AS174 AS6939 AS11164 AS11537 AS13536

AS557 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS557 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS557

5 downstreams

AS6056 AS14789 AS17152 AS22847 AS55032

AS557 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.
