AS6128 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 AS6128

5 upstreams

AS174 AS1299 AS3356 AS3737 AS7922

AS6128 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS6128 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS6128

3 downstreams

AS19720 AS20940 AS54004

AS6128 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.
