AS12615 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 AS12615

8 upstreams

AS174 AS1273 AS1299 AS3356 AS6762 AS9002 AS44901 AS59900

AS12615 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS12615 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS12615

24 downstreams

AS12436 AS29622 AS35773 AS38932 AS39401 AS41019 AS41624 AS42086 AS42100 AS42878 AS44313 AS47453 AS49040 AS49188 AS49849 AS50013 AS56906 AS59463 AS60182 AS199191 AS200024 AS203917 AS204210 AS205352

AS12615 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.
