We read every message. Replies usually take a few business days. This is not a 24/7 NOC.
What to include
- Bug reports: domain, record type, what you saw, what you expected, and the time (UTC if you can).
- Feature requests: the job you are trying to finish, not just a record type name.
- Privacy: say so in the subject. See the Privacy Policy.
- Abuse: timestamps, source IPs if you have them, and why you believe DNSFetch queries are involved.
For how the tool behaves, the FAQ is faster than email.
