Peers of AS16399

1 peers

AS10796

AS16399 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 AS16399

5 upstreams

AS174 AS3356 AS6461 AS40264 AS55089

AS16399 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS16399 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS16399

1 downstreams

AS22214

AS16399 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.
