AS9536 CNS-AS-AP Cloud Network Services HK Ltd

AS9536 (CNS-AS-AP) is registered to Cloud Network Services (HK) Ltd, a Hong Kong network. The registry picture is not entirely clean: the APNIC organisation record behind this AS maps to Macroview Telecom Limited, a long-standing Hong Kong managed-IT, cloud and systems-integration provider that became part of the HGC Global Communications group in 2019. The most likely reading is that the two names belong to the same corporate group, but the card should be read with that ambiguity in mind.

What it's used for

This is a small, deliberately-run network rather than a carrier or an eyeball ISP. RIS sees just 512 IPv4 addresses, announced as 202.182.224.0/23 together with the two /24s inside it, plus a single IPv6 /48 (2001:df0:e3::/48). Announcing a covering /23 alongside its components is a routine reachability hedge, not evidence of a large estate.

The interesting part is the interconnection. Seven BGP neighbours on only 512 addresses is a high ratio, and the adjacencies include NTT (AS2914) as an IPv4 and IPv6 upstream and the HKIX route servers, through which it reaches a spread of other networks. That is the shape of a network built for good reachability from a well-connected Hong Kong facility — a service or content platform sitting on a small, well-peered block — rather than one built to serve subscribers or to sell transit onward.

Notable

• Hong Kong ICT providers commonly hold a small AS like this for customer-facing hosted and managed services while their parent group runs the larger carrier network.
• IPv6 is present but minimal: one /48, matching the small IPv4 footprint.
