3 upstreams

AS21782 AS32505 AS40498

AS3912 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS3912 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS3912

3 downstreams

AS17153 AS40246 AS397535
