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 AS33660

1 peers

AS1000

AS33660 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 AS33660

2 upstreams

AS3356 AS7922

AS33660 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS33660 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS33660

66 downstreams

AS33660 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.
