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.

AS513 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 AS513

5 upstreams
AS174 AS6730 AS20965 AS25091 AS29222

AS513 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS513 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS513

6 downstreams
AS12654 AS20940 AS21449 AS25152 AS28810 AS48751

AS513 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.
