AS1000

AS17161 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 AS17161

5 upstreams

AS701 AS3356 AS4826 AS7474 AS15830

AS17161 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS17161 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS17161

0 downstreams

AS17161 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.
