AS51248 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 AS51248

6 upstreams

AS174 AS1299 AS3223 AS3257 AS9002 AS29208

AS51248 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS51248 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS51248

3 downstreams

AS62212 AS199669 AS215305

AS51248 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.
