自治系统（ASN，Autonomous System Number）是互联网上一组由同一机构统一路由策略管理的 IP 网络的编号， 是 IP 归属与信誉判断的基础单位。AS37963 由 ALIBABA-CN-NET - Hangzhou Alibaba Advertising Co.,Ltd. 运营，注册地 CN，对外宣告 813 个 BGP 前缀（IPv4 690 个 / IPv6 123 个）。
它被归类为机房 / 托管类网络——这类 ASN 多用于服务器托管、云主机或 CDN， 落在其上的 IP 通常不是真实住宅用户，常被风控系统视为机房 / 代理来源， 也是 VPN、代理、爬虫出口的常见落脚点。因此该网段下的 IP 纯净度普遍中等偏低， 用于注册、电商、社交等场景时更容易触发风控。
当前 IOC 信誉为干净（该 ASN 下有 4 个前缀命中威胁情报，密度 0.0000）。 信誉基于该 ASN 下命中威胁情报的前缀密度估算，**只反映网络整体洁净度**， 不代表其中每个 IP 的具体判定——单个 IP 的纯净度、是否 VPN/代理、地理位置请单独查询。

An Autonomous System Number (ASN) identifies a group of IP networks under a single organization's routing policy — the basic unit for IP ownership and reputation. AS37963 is operated by ALIBABA-CN-NET - Hangzhou Alibaba Advertising Co.,Ltd., registered in CN, and announces 813 BGP prefixes (690 IPv4 / 123 IPv6).
It is classified as hosting — ASNs of this kind are used for server hosting, cloud instances or CDNs. Their IPs are usually not real residential users, are commonly treated as datacenter / proxy sources by anti-fraud systems, and are a frequent home for VPN, proxy and crawler exits. IP cleanliness on these ranges tends to be low-to-medium and more likely to trigger risk controls on signup, e-commerce or social platforms.
The current IOC reputation is clean (4 prefixes under this ASN are flagged in threat intelligence, density 0.0000). It is estimated from the density of threat-flagged prefixes and reflects only the network's overall hygiene — not the verdict for any single IP. Check an individual IP for its cleanliness, VPN/proxy status and location.
