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 AS19855

1 peers
AS1000

AS19855 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 AS19855

8 upstreams
AS174 AS3356 AS3491 AS7473 AS7474 AS7922 AS12956 AS33491

AS19855 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS19855 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS19855

17 downstreams
AS543 AS11199 AS12222 AS13860 AS14514 AS15027 AS15126 AS16541 AS20340 AS20427 AS22775 AS23406 AS26428 AS33014 AS33054 AS40399 AS394301

AS19855 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.
