Peers of AS18400

3 peers

AS24516 AS64073 AS132847

AS18400 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 AS18400

2 upstreams

AS45177 AS56030

AS18400 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS18400 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS18400

17 downstreams

AS38037 AS45285 AS45633 AS45641 AS63519 AS131318 AS131455 AS132143 AS135142 AS136524 AS136559 AS137957 AS139020 AS141228 AS151475 AS153053 AS153850

AS18400 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.
