Upstreams of AS4185

1 upstreams

AS4185 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS4185 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS4185

0 downstreams

AS4185 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.
