Peers of AS15685

15 peers

AS1764 AS4455 AS8218 AS33891 AS49544 AS132337 AS212483 AS263444 AS24482 AS24940 AS29504 AS32590 AS39120 AS40994 AS51184

AS15685 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 AS15685

3 upstreams

AS1299 AS6939 AS42000

AS15685 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS15685 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS15685

7 downstreams

AS6881 AS48417 AS60592 AS198031 AS203376 AS205300 AS207153

AS15685 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.
