What does IP purity actually mean?
IP purity is not an ISO, RFC or industry certification, and there is no universal “clean score”. It is a judgement about an egress IP across history, network identity, reputation and environment consistency.
“Clean” does not mean the IP has never been used, and residential broadband is not automatically safe. The useful question is whether the signals exceed what your target platform will tolerate for this specific workload.
Which six signal groups matter?
Instead of chasing a mysterious total score, separate the evidence. A single abnormal signal can explain why a page opens but registration or payment fails.
- Network type: residential, mobile, hosting, enterprise or CDN.
- History: abuse, spam, fraud and blocklist records.
- Anonymity: proxy, encrypted tunnel, Tor and shared egress.
- Native IP: whether registration country and usage region align.
- Consistency: DNS location, WebRTC addresses, browser time zone and language.
- Business requirements: the target platform’s actual rules for region, network type and account history.
How do I check whether an IP is clean?
Confirm the browser’s actual egress first, then inspect network type, proxy flags, native IP, reputation and DNS/WebRTC consistency. Do not rely on one total score, and do not treat one result as a permanent state.
For the full framework, read the existing IP purity guide; when validating a proxy, also check VPN / proxy detection and the DNS leak test.
Frequently asked questions
What score counts as a clean IP?
There is no universal threshold. Different checkers weight signals differently, and the same score means different things in different businesses. Read the individual signals and validate against the target platform.
Are residential IPs always clean?
No. Residential describes the network type, not history. Abused residential addresses and shared home broadband can still carry risk.
Why do different purity checkers disagree?
They use different databases, update schedules, proxy samples, blocklist sources and scoring algorithms. The disagreement itself is a reason to cross-check.
Does this read my account or device?
No. The page reads the public egress and public network data used to visit this site; browser-side WebRTC collection stays on your machine.
