AS22742 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 AS22742

5 upstreams

AS174 AS3257 AS11164 AS11537 AS32097

AS22742 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS22742 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS22742

21 downstreams

AS29 AS167 AS3481 AS3592 AS3606 AS3719 AS11598 AS12024 AS13796 AS15124 AS25691 AS29867 AS40149 AS54973 AS55032 AS62548 AS393337 AS394655 AS394688 AS394858 AS397720

AS22742 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.
