About & privacy
n0.wiki is a free, non-commercial IP lookup tool: no ads, no paywall, no sign-up.
Why this site exists
Most IP lookup sites give a verdict without the reasoning: one database says residential, another says datacenter, and you are left guessing. n0.wiki shows the source, fact class and confidence of every finding; when sources disagree with no majority, it lists every disagreement instead of picking one for you. See sources and scoring.
Why there is no CDN
The site has to see your real exit address and TLS handshake, because that is what it tests. Behind a CDN or reverse proxy it would only see the CDN's address. So visitors connect to our server directly.
What we collect and for how long
| Data | Purpose | Retention |
|---|---|---|
| Server access logs (IP, time, request path, user agent) | Troubleshooting and abuse prevention | Rotated daily by system default, deleted after about 14 days |
| Lookup results | Avoid querying the same IP repeatedly and reduce calls to third-party sources | In-memory only, at most 24 hours (cleared on data update or service restart; results with a failed source are kept for 90 seconds) |
| DNS leak test observations | Produce the test result | Deleted automatically after 15 minutes |
| WebRTC candidates | The current verdict | Not stored |
No tracking cookies, no analytics or ad scripts, no user profiles, and no selling or sharing of data.
When your IP goes to third parties
- When the page opens: only local databases and registry/routing infrastructure such as RIPEstat, RDAP and Team Cymru.
- When you click "run deep check": your IP goes to third-party intelligence sources (proxycheck, AbuseIPDB, ipapi.is and others); the page lists them first.
- The WebRTC test contacts Google's and Cloudflare's public STUN servers.
- Port exposure details query Shodan InternetDB and GreyNoise.
Result pages are kept out of search engines
Result URLs contain an IP (?ip=…). Search engines are told not to index any such URL; only the parameter-free information pages may be indexed.
