Part 1: What Is a “Clean IP”? #
In proxy and antidetect-browser scenarios (e.g. AdsPower), a “clean IP” means an IP that is:
- ๐ซ Not on a blacklist (e.g. Spamhaus)
- ๐ Low fraud score
- ๐ A “native” residential IP, not an easily detected datacenter IP
- ๐ต๏ธ Not flagged as proxy / VPN / Tor / datacenter
- ๐ Geolocation, ASN and DNS all consistent, no leaks
A single tool usually covers only one angle; in practice, cross-checking several tools confirms IP cleanliness.
Part 2: Tool Overview #
| Tool | Positioning | Core purpose | Main audience | Free tier |
|---|---|---|---|---|
| ping0.cc | IP cleanliness / native IP check | Native IP, IP risk value, geolocation | Chinese proxy users, self-hosted VPS users | Free (web) |
| ipinfo.io | IP data intelligence platform | Location, ASN, privacy flags, API | Developers, enterprises | 50k req/month |
| IPQS (ipqualityscore.com) | Fraud detection platform | Fraud Score 0-100, proxy/VPN detection | Enterprises, e-commerce, finance | 1,000 lookups |
| whoer.net | IP leak / anonymity check | DNS/WebRTC leaks, blacklist, anonymity score | General users, VPN users | Free (web) |
Part 3: Core Features of Each Tool #
1. ping0.cc โ Native IP / IP risk value (popular in the Chinese community) #
- IP risk value: assigns a risk score to an IP
- Native IP check: residential vs datacenter/broadcast IP
- Geolocation: high-precision location and ASN
- Reverse domain lookup, latency/ping/trace, ASN change monitor
- โ ๏ธ Privacy note: some media claim it may log your real IP
2. ipinfo.io โ IP data intelligence (developer/enterprise) #
- Geolocation: city/region/country/coordinates/timezone
- ASN + company/org, mobile carrier, hosting flag
- Privacy Detection: is_proxy / is_vpn / is_tor / is_res_proxy flags
- Abuse contact, hosted domains, WHOIS, ranges
- API + database downloads (JSON/CSV/MMDB/Parquet), 99.99% uptime, 50โ200ms
- Product tiers: Lite โ Core (22 attributes) โ Max (43) โ Enterprise (55)
3. IPQS (ipqualityscore.com) โ Fraud Score 0-100 (fraud detection) #
- Fraud Score: 0โ100, >85 is high risk โ the most direct “IP cleanliness” score
- Risk Score, Recent Abuse, Abuse Velocity, Bot Activity, Search Crawler
- Proxy / VPN / Tor detection
- Beyond IP: Email validation, Phone validation, URL scanning, device fingerprinting
- Ideal for high-risk scenarios like checkout, signup, login
4. whoer.net โ IP leak / anonymity score #
- Anonymity score (e.g. “Your disguise: 90%”), itemized deductions
- DNS leak, WebRTC leak detection (does the VPN leak your real IP?)
- Blacklist detection (connects to Spamhaus)
- Browser fingerprint, Flash/Java/ActiveX, open proxy ports, Tor detection
- Ideal for verifying whether a VPN/proxy truly hides your real IP
Part 4: Feature Comparison #
| Check | ping0.cc | ipinfo.io | IPQS | whoer.net |
|---|---|---|---|---|
| IP geolocation / ISP / ASN | โ | โ | โ | โ |
| Fraud Score | โ risk value | โ indirect | โ 0-100 | โ |
| Native / residential IP | โ core | โ indirect | โ | โ |
| Proxy / VPN / Tor detection | โ | โ | โ | โ |
| Blacklist | โ | โ | โ | โ |
| DNS / WebRTC leak | โ | โ | โ | โ |
| Anonymity score | โ | โ | โ | โ |
| Developer API | โ | โ core | โ | โ |
| Chinese UI | โ | โ | โ | โ |
Part 5: Recommended Use Cases #
| Scenario | Recommended tool | Why |
|---|---|---|
| Verify “native IP” after buying residential proxies | ping0.cc | Most direct native-IP check |
| Fraud score before checkout / signup | IPQS | Fraud Score is most intuitive |
| Programmatic IP data integration | ipinfo.io | Most mature API + database |
| Check VPN/proxy for IP leaks | whoer.net | DNS/WebRTC leak + anonymity score |
| Full cross-validation of cleanliness | All four | Cover each other’s blind spots |
โ ๏ธ Notes #
| Note | Description |
|---|---|
| No single tool is complete | Each has blind spots; cross-check multiple tools |
| Fraud Score is not absolute | It is an estimate and may have false positives |
| “Native IP” is debatable | Tools define “native” differently; results may conflict |
| Privacy risk | Query tools may log your IP (ping0.cc has been questioned) |
| Free tier is limited | API tools (ipinfo, IPQS) require payment beyond free quota |
