- Understand visibility: learn what parts of your connection are publicly exposed
- Run quick checks: lightweight tools for fast answers, not full diagnostics
FAQ (quick answers)
- Do you log or store my IP address?
Most tools run entirely in your browser. If a tool needs server processing (for example, DNS lookups), that’s clearly disclosed on the tool’s page. - Is my IP address private?
Your public IP is already visible to websites you visit. These tools show you what’s exposed—they don’t increase your visibility. - Why does my IP change sometimes?
IP addresses can change due to ISP policies, mobile networks, VPNs, or reconnecting your router. This is normal behavior. - Do you support IPv6?
Yes. If your connection supports IPv6, the IP tool will show it. If not, you’ll see IPv4 only. - Are these full diagnostic tools?
No. These are lightweight utilities for quick checks and visibility, not replacements for full network diagnostics. - Do I need an account or install anything?
No account, no installs. Everything runs in the browser, with no watermarks or tracking.
