AS39912 peers with these other Autonomous Systems.

Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.

Upstreams of AS39912

3 upstreams

AS3223 AS8540 AS33891

AS39912 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS39912 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS39912

10 downstreams

AS41905 AS50255 AS51413 AS59456 AS61155 AS61201 AS61438 AS62373 AS207131 AS212640

AS39912 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.
