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.
AS397990 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.
AS397990 uses these Autonomous Systems as its upstreams.
An upstream (or transit provider) is another AS that AS397990 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.
AS397990 has no downstreams recorded.
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.
