Peers of AS21150

0 peers

AS21150 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 AS21150

2 upstreams

AS21150 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS21150 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS21150

6 downstreams

AS21150 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.
