什么是 IP 纯净度检测
IP 纯净度检测判断一个出口 IP「像不像真实终端用户网络」:是住宅 / 移动宽带,还是机房、云主机、CDN 一类共享基础设施,或是 VPN / 代理 / Tor 出口。这决定了它在注册风控、支付、流媒体解锁和 AI 服务这些场景下容不容易被拦截。
判定依据有哪些
- ASN 归属与类型:机房 / 云 / CDN / 运营商,基于自建 ASN 数据集判断;
- 威胁情报命中密度:所属网段是否命中恶意 IOC,以及命中的密集程度;
- 住宅代理特征:是否落在已知的住宅/移动代理服务商网段;
- 反向 DNS 与被动 DNS 历史:主机名规律、历史承载域名数量是否更像服务器而非终端用户;
- VPN / 代理 / Tor 识别:基于 AS 名称库、匿名器密集 ASN 与闭环受控采集验证。
每一项证据都在结果页单独列出(判定依据 / 证据链),可逐条核对来源与置信度,不是不可解释的黑盒分数。
常见问题
IP 纯净度评分是怎么算出来的?
综合多个自建信号:ASN 类型(机房/住宅/移动)、威胁情报命中密度、住宅代理特征库、反向 DNS、被动 DNS 历史等。每一项的加减分都单独列出,可在结果页的判定依据里逐条核对,不是黑盒分数。
纯净度高就一定不是 VPN 吗?
不一定。纯净度衡量的是「像不像真实终端用户网络」,VPN/代理/Tor 是单独识别的布尔特征,两者会同时展示——一个住宅代理出口可能纯净度看起来不低,但仍会被标记为高风险。
支持 IPv6 吗?
支持。IPv4 / IPv6 都能查询,双栈出口(同时有 v4 和 v6 公网地址)会分别列出,并检测两者是否一致。
只看纯净度够吗?
不够。纯净度只是静态画像,想知道分流出口是否一致、DNS/WebRTC 是否泄漏、AI 服务是否可达,运行完整深度检测。
What is an IP cleanliness check
An IP cleanliness check judges how much an exit IP looks like a real end-user network — residential / mobile broadband versus shared infrastructure such as datacenters, cloud instances and CDNs, or a VPN / proxy / Tor exit. That distinction drives how likely it is to be blocked by sign-up risk control, payments, streaming unblocking and AI services.
What the verdict is based on
- ASN ownership and type: hosting / cloud / CDN / ISP, judged from a self-built ASN dataset;
- Threat-intel hit density: whether the network range hits known malicious IOCs and how densely;
- Residential-proxy fingerprints: whether it falls in a known residential/mobile proxy provider's range;
- Reverse DNS and passive-DNS history: hostname patterns and how many domains it has historically served;
- VPN / proxy / Tor detection: from an AS-name database, anonymizer-dense ASNs and closed-loop controlled collection.
Every signal is listed individually on the result page (evidence chain) with its own source and confidence — not an unexplainable black-box score.
FAQ
How is the IP cleanliness score calculated?
It combines several self-built signals: ASN type (datacenter / residential / mobile), threat-intel hit density, residential-proxy fingerprint databases, reverse DNS and passive-DNS history. Every contributing signal is listed on the result page's evidence chain — it is not a black-box number.
Does a high cleanliness score mean it isn't a VPN?
Not necessarily. Cleanliness measures how much an IP looks like a real end-user network; VPN/proxy/Tor are separate boolean signals shown alongside it — a residential-proxy exit can score reasonably clean while still being flagged high-risk.
Does it support IPv6?
Yes. Both IPv4 and IPv6 are supported; a dual-stack exit (public v4 and v6 both present) lists each address and checks whether the two are consistent.
Is the cleanliness score enough on its own?
No — it is a static profile only. To confirm split-exit consistency, DNS/WebRTC leaks and AI reachability, run the full deep check.
