The network's position in the inter-domain routing hierarchy: its customer cone, connectivity, and transit role.
Inferred AS-level relationships: 1 upstream providers, 0 peers and 0 downstream customers. The graph shows the largest few of each; the lists link through.
exchange traffic directly
None recorded.
buy transit from it
None recorded.
Relationships are inferred from BGP by CAIDA and refreshed monthly. Transit links are well captured; some private and IXP peering is under-observed, so peer counts are a lower bound.
How well this network secures and documents its BGP announcements — RPKI origin validation, IRR registration, and an overall hygiene score.
Measured share of this network's users reaching the Internet over IPv6 (APNIC end-user measurement, Japan).
Has working IPv6 connectivity, even if it isn't always chosen.
IPv6 wins when a destination is dual-stacked — the real-world usage rate.
