Upstreams
AS23767 connects to the global Internet via at least 5 upstream providers. In this setup, AS23767 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.
Downstreams
AS23767 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
