Peers
AS24349 actively fosters the following peering relationships that enhance network performance through direct, settlement-free traffic exchange. Even with a modest number of peers, each connection serves as a strategic asset—optimizing routing, reducing latency, and minimizing transit costs.
Upstreams
There are currently no upstream providers for AS24349. This means the network doesn’t subscribe to traditional upstream services for global connectivity. Instead, it likely relies on direct peering or its own infrastructure to reach external networks. While this can reduce transit costs, it requires a robust peering strategy to maintain broad reachability and ensure redundancy.
Downstreams
AS24349 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
