An upstream (or transit provider) is another AS that AS23881 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS23881

0 downstreams

AS23881 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.
