What this tool does not do / Limits

This tool is a pasted-record format validator only. It performs no live DNS lookup and cannot confirm any record is published.

Frequently asked questions

Does this look up my domain?

No. It only validates the format of records you paste; it never queries DNS.

Does valid format mean the record is live?

No. A well-formed record may still not be published; check with your DNS provider.
