AS12727 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 AS12727

5 upstreams

AS174 AS6762 AS6939 AS15557 AS30781

AS12727 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS12727 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS12727

2 downstreams

AS208574 AS208719

AS12727 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.
