Peers

AS1 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.

AS11537

Upstreams

AS1 connects to the global Internet via at least 5 upstream providers. In this setup, AS1 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.

AS29132 AS136617 AS262544 AS263301 AS271758

Downstreams

AS1 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
