Peers of AS55900

14 peers

AS1000 AS2500 AS18106 AS49544 AS4775 AS6939 AS8220 AS9002 AS24482 AS35280 AS137409 AS59105 AS60068 AS140627

AS55900 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 AS55900

4 upstreams

AS1299 AS2497 AS2914 AS3356

AS55900 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS55900 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS55900

8 downstreams

AS24277 AS45679 AS55899 AS63774 AS63800 AS131951 AS135607 AS146986

AS55900 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.
