Hong Kong SAR China · Autonomous System
Where this network meets others — public exchange points, colocation facilities, and declared peering capacity.
The network's position in the inter-domain routing hierarchy: its customer cone, connectivity, and transit role.
Inferred AS-level relationships: 10 upstream providers, 50 peers and 31 downstream customers. The graph shows the largest few of each; the lists link through.

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, Germany).
Has working IPv6 connectivity, even if it isn't always chosen.
IPv6 wins when a destination is dual-stacked — the real-world usage rate.
Currently announced prefixes, live from RIPEstat.
Invalid announcements have a ROA on file but the origin AS or prefix length doesn't match it — usually a stale ROA or misconfiguration rather than an active hijack.
90 prefixes currently seen by RIPEstat.
