Upstreams of AS320

1 upstreams

AS320 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS320 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS320

0 downstreams

AS320 has no downstreams recorded.

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.
