AS9810 TNSNET Beijing Times Netstar Technology Co.,Ltd

AS9810 (TNSNET) is held by Beijing Times Netstar Technology Co., Ltd, a small Beijing-based network and data-centre operator registered out of the Guomao district. It is a modest commercial network with a single contiguous slice of CNNIC address space.

What it's used for

RIS sees 6 IPv4 prefixes carrying 5,120 addresses and no IPv6, reached through only 2 BGP neighbours. Every announced prefix falls inside the 211.155.160.0 - 211.155.191.255 range registered to TNSNET, and the announcements are simply that block chopped into a /21, a /22 and four /23s. There is nothing here belonging to a third party and nothing scattered across other registries, so this is a self-contained operator using its own allocation, not an aggregator of other people's space. Five thousand addresses behind two upstreams is the shape of an IDC/ISP serving hosted servers and connected business customers: too much space to be one company's office, far too little (and far too few neighbours) to be a carrier of any weight. Chinese network directories list it in the IDC/ISP category, which matches the routing evidence.

Notable

• The whole footprint is one registry allocation, deaggregated for routing rather than grown by acquisition — a stable, unchanged inventory.
• Two upstreams and three observed peers is a minimal-viable multihoming posture; there is no peering ambition here.
• No IPv6 is announced.
