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 AS7671

3 peers

AS2516 AS6939 AS59105

AS7671 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 AS7671

3 upstreams

AS2497 AS2914 AS9607

AS7671 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS7671 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS7671

2 downstreams

AS2506 AS63785

AS7671 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.
