AS16276 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 AS16276

23 upstreams

AS174 AS1239 AS1273 AS1299 AS2914 AS3356 AS4637 AS4755 AS5511 AS6453 AS6461 AS6762 AS7195 AS7922 AS9002 AS12703 AS12956 AS23470 AS29467 AS31027 AS31103 AS52025 AS328066

AS16276 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS16276 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

AS16276 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.
