AS35228 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 AS35228

3 upstreams

AS3257 AS5089 AS12956

AS35228 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS35228 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS35228

4 downstreams

AS29180 AS39060 AS50063 AS57850

AS35228 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.
