Frequently Asked Questions
- Does checking a domain name register it in search histories?
- No, queries are fetched using secure APIs that inspect public registers without recording search intentions.
- How does What Is My IP work?
- It makes a direct client-side request to secure geolocation resolvers to capture your IP and network details.
- Are SSL checks updated in real-time?
- Yes, we connect directly to the target hostname to query the live certificate chain returned by the server.
