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 AS18988

3 upstreams

AS174 AS6461 AS6939

AS18988 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS18988 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS18988

3 downstreams

AS27256 AS32204 AS398157

AS18988 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.
