AS44066 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 AS44066

6 upstreams

AS174 AS1299 AS2914 AS3257 AS3320 AS39686

AS44066 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS44066 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS44066

19 downstreams

AS1921 AS31400 AS44051 AS49532 AS50198 AS59939 AS200249 AS204119 AS205948 AS206880 AS207298 AS208621 AS209169 AS212302 AS213726 AS214036 AS214895 AS215741 AS216093

AS44066 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.
