Peers of AS2

2 peers

AS29091 AS37254

AS2 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 AS2

10 upstreams

AS34 AS37613 AS37628 AS41837 AS45609 AS52752 AS141975 AS203794 AS266893 AS270792

AS2 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS2 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS2

1 downstreams

AS37280

AS2 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.
