IP ranges are the different blocks of IP addresses advertised by an Autonomous System (AS). These ranges can be used by the same organization operating the AS, or by different organizations.

Peers of AS3

4 peers

AS293 AS6939 AS22608 AS141647

AS3 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 AS3

10 upstreams

AS174 AS3356 AS7015 AS10578 AS16713 AS35978 AS59404 AS63483 AS265886 AS268142

AS3 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS3 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS3

1 downstreams

AS54755

AS3 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.
