Upstreams
AS4725 connects to the global Internet via at least 2 upstream providers. In this setup, AS4725 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.
Downstreams
AS4725 serves as a transit provider the following ASes, delivering the BGP routes needed for global connectivity. This downstream relationship underscores AS4725's role in extending Internet access beyond its own infrastructure.
