这个 ASN 是什么
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。AS3491 由 PCCWG-APAC-HK - PCCW Global (HK) Ltd. 运营，注册地 HK，对外宣告 536 个 BGP 前缀（IPv4 500 个 / IPv6 36 个）。
类型与纯净度含义
它被归类为未知类网络——通常对应真实终端用户接入（家宽 / 移动）。 这类网段的 IP 纯净度普遍较高，但具体到单个 IP 仍可能因被滥用、做住宅代理或被列入威胁情报而异常。
IOC 信誉
当前 IOC 信誉为干净。 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。

What is this ASN?
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. AS3491 is operated by PCCWG-APAC-HK - PCCW Global (HK) Ltd., registered in HK, and announces 536 BGP prefixes (500 IPv4 / 36 IPv6).
Type & cleanliness
It is classified as unknown — typically real end-user access (home broadband / mobile). IPs here tend to be cleaner, though an individual IP can still be flagged if it is abused, used as a residential proxy, or listed in threat intelligence.
IOC reputation
The current IOC reputation is clean. 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.
