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。AS4134 由 CHINANET-BACKBONE - No.31,Jin-rong Street 运营，注册地 CN，对外宣告 1356 个 BGP 前缀（IPv4 729 个 / IPv6 627 个）。
它被归类为住宅宽带类网络——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。
当前 IOC 信誉为干净（该 ASN 下有 11 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. AS4134 is operated by CHINANET-BACKBONE - No.31,Jin-rong Street, registered in CN, and announces 1356 BGP prefixes (729 IPv4 / 627 IPv6).
It is classified as residential ISP — 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.
The current IOC reputation is clean (11 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.
