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 AS30851

2 peers

AS24482 AS49544

AS30851 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 AS30851

3 upstreams

AS12741 AS12912 AS15694

AS30851 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS30851 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS30851

11 downstreams

AS24578 AS43837 AS43929 AS51769 AS51931 AS59990 AS60189 AS197187 AS199965 AS201451 AS208556

AS30851 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.
