Peers of AS4581

0 peers

AS4581 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 AS4581

4 upstreams

AS174 AS3356 AS6939 AS52025

AS4581 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS4581 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS4581

15 downstreams

AS11929 AS13341 AS16697 AS36779 AS40673 AS46755 AS55056 AS62723 AS393668 AS395311 AS397092 AS397323 AS397479 AS399802 AS401718

AS4581 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.
