AS1280 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 AS1280

4 upstreams

AS1299 AS2914 AS6939 AS7922

AS1280 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS1280 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS1280

3 downstreams

AS3557 AS24151 AS30133

AS1280 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.
