Peers of AS12660

0 peers

AS12660 has no peers recorded.

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 AS12660

2 upstreams

AS6736 AS42337

AS12660 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS12660 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS12660

0 downstreams

AS12660 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.
