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 AS18126

16 peers

AS2500 AS4713 AS9002 AS18106 AS1828 AS4775 AS4777 AS6939 AS8220 AS17639 AS49544 AS59105 AS137409 AS140627 AS24482 AS38001

AS18126 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 AS18126

5 upstreams

AS1299 AS2497 AS2516 AS2519 AS2914

AS18126 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS18126 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS18126

1 downstreams

AS146985

AS18126 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.
