BGP Peers

No settlement-free peers observed

CAIDA AS-Relationships lists no peer (p2p) ASes — common for stub networks that buy all transit and don't peer publicly, or for content networks whose peering is over private interconnects not visible to public route collectors.

Customers

Leaf / stub network (no transit customers)

No ASes buy transit from this ASN — typical for content networks (Cloudflare, Google, Meta, Netflix), enterprise and stub eyeball ASes. If this is a transit ISP, customer relationships may be classified in the next CAIDA weekly snapshot.
