Peers of AS7668

8 peers
AS1828 AS4777 AS6939 AS49544 AS17639 AS20485 AS24482 AS59105

AS7668 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 AS7668

6 upstreams
AS2497 AS2519 AS2914 AS4713 AS17534 AS17676

AS7668 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS7668 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS7668

5 downstreams
AS4711 AS17932 AS18123 AS24260 AS24264

AS7668 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.
