Peers of AS131965

2 peers

AS59105 AS4777

AS131965 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 AS131965

3 upstreams

AS1299 AS2497 AS4713

AS131965 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS131965 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS131965

0 downstreams

AS131965 has no downstreams recorded.

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.
