AS18046 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 AS18046

8 upstreams

AS174 AS4637 AS4780 AS9002 AS10133 AS17408 AS21859 AS23764

AS18046 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS18046 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS18046

11 downstreams

AS984 AS18413 AS24169 AS24172 AS38851 AS63893 AS63899 AS131584 AS131655 AS133948 AS136897

AS18046 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.
