Peers of AS40021

0 peers

AS40021 has no peers recorded.

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 AS40021

3 upstreams

AS174 AS3356 AS46887

AS40021 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS40021 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS40021

0 downstreams

AS40021 has no downstreams recorded.

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.
