Peers of AS6802

9 peers

AS3303 AS5405 AS6939 AS8218 AS8280 AS49544 AS137409 AS208972 AS32590

AS6802 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 AS6802

5 upstreams

AS8262 AS8717 AS8866 AS20965 AS21320

AS6802 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS6802 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS6802

7 downstreams

AS5421 AS8745 AS28949 AS41352 AS47174 AS48155 AS49704

AS6802 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.
