Peers of AS55

0 peers

AS55 has no peers recorded.

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 AS55

4 upstreams

AS174 AS3356 AS11164 AS11537

AS55 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS55 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS55

2 downstreams

AS69 AS46274

AS55 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.
