Peers of AS766

15 peers

AS3303 AS5400 AS9002 AS13030 AS22356 AS29680 AS33891 AS35280 AS6424 AS6939 AS8220 AS8426 AS37468 AS37721 AS49544

AS766 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 AS766

4 upstreams

AS174 AS3356 AS20965 AS21320

AS766 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS766 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS766

21 downstreams

AS288 AS2114 AS13041 AS15488 AS15630 AS25285 AS25354 AS31951 AS34285 AS34511 AS43697 AS44593 AS49851 AS197829 AS198096 AS198853 AS198878 AS200521 AS205580 AS208597 AS210158

AS766 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.
