AS62523 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 AS62523

3 upstreams

AS174 AS3257 AS6939

AS62523 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS62523 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS62523

6 downstreams

AS1420 AS7386 AS26875 AS40121 AS40642 AS399440

AS62523 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.
