By using D.PRO you agree to the following.
Service
D.PRO is a free, informational tool that queries public DNS and shows how a record change is propagating. It is provided as-is and as-available, with no warranty and no service-level guarantee. It may change or be unavailable at any time.
Accuracy
Results are best-effort snapshots of what public resolvers returned at query time. DNS is distributed and cached; readings can lag reality and individual resolvers can be slow or wrong. Do not rely on D.PRO as the sole basis for a production cutover decision.
Fair use
The backend enforces per-client rate limits. Do not attempt to bypass them, script bulk or automated runs, or use the tool to probe or attack third-party infrastructure. Access may be throttled or blocked for abuse.
Liability
To the maximum extent permitted by law, the project and its maintainer are not liable for any loss or damage arising from use of, or inability to use, D.PRO.
Changes
These terms may be updated; the "last updated" date will change. Continued use after a change means you accept it.
