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 AS8508

5 peers

AS3303 AS6939 AS24482 AS28917 AS49544

AS8508 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 AS8508

3 upstreams

AS8501 AS15744 AS196844

AS8508 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS8508 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS8508

0 downstreams

AS8508 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.
