About this network

AS9814 (FibrLINK) is held by Beijing FibrLINK Networks Co., Ltd, the communications arm of the State Grid Corporation of China (SGCC). FibrLINK commercialises the fibre capacity that runs alongside the national power grid, selling network services, data-centre capacity and enterprise connectivity.

What it's used for

RIS sees 137 IPv4 prefixes carrying 78,848 addresses and no IPv6, announced through just 6 BGP neighbours. The inventory is a 125.98.128.0/17 plus a dense collection of /19–/22s across 211.160, 210.72, 210.77 and 211.99 — CNNIC space deaggregated far past what routing needs, which is what happens when blocks are handed out in small pieces to hosted customers and internal grid systems. The reverse DNS makes the dual character plain: one sampled address resolves to mail.sgcc.com.cn, State Grid's own corporate mail, while another lands on an unrelated third-party consumer website. So the same AS carries both the parent utility's internal-facing services and commercially hosted content. Six neighbours confirms it is not a transit carrier despite the fibre assets — it terminates traffic for the grid and for paying tenants.

Notable

• The fibre comes from the power grid: SGCC's transmission network is one of the largest in the world, and FibrLINK is how the spare strands on it are monetised.
• sgcc.com.cn rDNS in this space shows what it carries, not who holds it — but here the carrier and the parent are the same group, so the two agree.
• No IPv6 despite the size of the IPv4 holding.
