What n0.wiki does
n0.wiki is a free, non-commercial IP lookup and IP reputation checker. It looks up your current exit IP as soon as the page opens, and you can enter any IPv4 or IPv6 address. Results combine more than thirty data sources, and every finding shows its fact class, source and confidence: missing data lowers confidence, it never raises the score.
IP purity score
Blocklists, abuse history, anonymization, geolocation agreement and port exposure combined into one score, with caps for datacenter, VPN, proxy and Tor exits.
DNS leak test
Our own authoritative DNS sees your recursive resolver and its ECS subnet, and tells whether lookups bypass your VPN and expose your real ISP.
WebRTC leak test
Collects ICE candidates in your browser to check whether WebRTC exposes a local or real exit address outside your proxy.
FAQ
- What is the IP purity score?
- A single 0–100 score, higher is better. Without enough evidence (no blocklist answer, coverage below 60%, or fewer than two security dimensions) no score is given and the reason is shown. See scoring.
- Why do datacenter and VPN IPs max out at 54?
- Most platforms treat datacenter and VPN exits more strictly. Since scoring model 2.2, both are capped at 54, the same band as residential proxies. It does not mean they are malicious.
- What is a DNS leak?
- If your lookups are still resolved by your real ISP while you use a VPN, that ISP sees what you visit. A resolver IP that differs from your exit IP is not a leak by itself. See the DNS leak test.
- Do you log my IP?
- No profiles, no tracking. By default only local databases and registry/routing infrastructure are queried; your IP goes to third-party intelligence only when you click the deep check. See about & privacy.
