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 AS27257

7 peers

AS3303 AS19151 AS2516 AS24482 AS29838 AS53828 AS395383

AS27257 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 AS27257

2 upstreams

AS174 AS6939

AS27257 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS27257 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS27257

4 downstreams

AS14712 AS46323 AS47019 AS395853

AS27257 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.
