Peers of AS1590

0 peers

AS1590 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 AS1590

1 upstreams

AS27064

AS1590 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS1590 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS1590

0 downstreams

AS1590 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.
