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 AS195

1 peers

AS293

AS195 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 AS195

3 upstreams

AS2152 AS2153 AS22773

AS195 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS195 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS195

5 downstreams

AS1909 AS2641 AS12148 AS22213 AS46985

AS195 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.
