About this ASN.
AS37963 is Alibaba Cloud's primary China-domestic network (Aliyun Computing), registered through APNIC to Hangzhou Alibaba Advertising Co., Ltd. and sitting within the CNNIC ASN block. It is the largest of the Alibaba ASNs by IP volume, originating roughly 813 IPv4 prefixes and ~143 IPv6 prefixes for a very large pool of around 13 million IPv4 addresses, with sample hostnames resolving under aliyun.com. RPKI coverage is clean, and it is present at a small number of mostly China-domestic IXPs; CAIDA ranks it #12503 as a single-ASN cone — enormous address space but essentially no onward transit. It is the corporate sibling of the international Alibaba Cloud ASN AS45102, with which it shares the ALIBABA-CN-NET as-name. As multi-tenant hyperscale cloud the standard caveats apply: the address pool is large and shared, IPs are dynamically reassigned among tenants, and reputation must attach to the current tenant rather than to Alibaba. Like the large China backbones it appears in scanning and abuse datasets roughly in proportion to its very large size and tenant base, which should be read neutrally and dated — a function of scale and tenant behavior, not operator intent. The public APNIC aut-num exposes no creation date, so the allocation date is recorded as unknown rather than guessed.
