Peers of AS4665

0 peers

AS4665 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 AS4665

3 upstreams

AS3786 AS4766 AS9318

AS4665 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS4665 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS4665

0 downstreams

AS4665 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.
