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 AS19

0 peers

AS19 has no peers recorded.

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 AS19

3 upstreams

AS62 AS3356 AS6461

AS19 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS19 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS19

0 downstreams

AS19 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.
