Peers of AS18092

3 peers

AS6939 AS35280 AS59105

AS18092 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 AS18092

3 upstreams

AS2516 AS4713 AS17676

AS18092 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS18092 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS18092

1 downstreams

AS45677

AS18092 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.
