AS39326 peers with these other Autonomous Systems.

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 AS39326

3 upstreams

AS1299 AS2914 AS39686

AS39326 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS39326 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS39326

20 downstreams

AS5500 AS8330 AS15689 AS16174 AS35399 AS39545 AS41400 AS41489 AS47227 AS50888 AS57650 AS59565 AS60382 AS199448 AS200652 AS201226 AS202020 AS209113 AS212413 AS212729

AS39326 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.
