Support · running on kindness
Lookups are free. Electricity is not.
No ads, no tracking, no paywall — a hundred lookups still cost you nothing, while the server and the DNS experiment field run on the maintainer's own pocket. If ns.fs.kg has ever traced a delegation chain for you or caught a serial number that refused to sync, scan the code and buy the maintainer a coffee. It keeps the generator humming.
The payee shows "Xiaokang" — that's the maintainer. Any amount works, and if you would rather not spend, a friendly email saying "nice tool" fills the meter just as well.
Contact · straight to the inbox
Say it plainly —
one message is enough.
A record that looks wrong, resolver behavior that makes no sense, a feature the lab should have, or you just want to complain about something. Write it here. No signup, no captcha — the message goes straight to the maintainer's inbox, and the reply lands in whatever address you leave.
- One message, nothing else: you will not be added to any list, and it will never be used for marketing or notifications.
- Enough context to act on: to keep the report traceable, the message carries the page URL and browser identity at the time you sent it, so the issue can be reproduced.
- Reply time: usually as soon as it is read, sometimes a day or two when things are busy. For resolution issues, paste the domain, the record type and the output you saw.
The form will not open or will not submit?
Just write to ns@ok.fs.kg — it reaches the same inbox.
