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 AS5050

4 peers

AS293 AS1000 AS6939 AS19151

AS5050 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 AS5050

4 upstreams

AS174 AS3356 AS11164 AS11537

AS5050 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS5050 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS5050

14 downstreams

AS9 AS1206 AS1207 AS3783 AS4130 AS7925 AS11009 AS12118 AS18572 AS19281 AS23102 AS27604 AS36407 AS63472

AS5050 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.
