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 AS12213

7 peers

AS1000 AS6939 AS19151 AS25091 AS49544 AS137409 AS23473

AS12213 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 AS12213

4 upstreams

AS3356 AS6461 AS7018 AS49915

AS12213 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS12213 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS12213

36 downstreams

AS1379 AS3573 AS10493 AS11775 AS13690 AS14132 AS15248 AS16910 AS18584 AS18679 AS20201 AS21701 AS23280 AS26584 AS26842 AS29802 AS29971 AS30031 AS40261 AS40372 AS54766 AS197594 AS393548 AS394880 AS396002 AS396104 AS396163 AS396252 AS396333 AS398014 AS398172 AS398863 AS399321 AS401208 AS401577 AS402438

AS12213 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.
