Upstreams of AS4557

4 upstreams

AS4557 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS4557 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS4557

14 downstreams

AS4557 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.
