Peers

AS15248 does not have any direct peering agreements. Instead, its global connectivity is achieved through transit providers. While this setup ensures comprehensive reach, future peering could reduce latency and optimize route efficiency.

Upstreams

AS15248 connects to the global Internet via at least 3 upstream providers. In this setup, AS15248 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.

Downstreams

AS15248 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
