AS1853 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 AS1853

4 upstreams

AS1121 AS1764 AS6939 AS20965

AS1853 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS1853 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS1853

47 downstreams

AS1853 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.
