Test if Workers actually leaking queries when used to proxy against NextDNS.
- Create a new Workers using doh-cf-workers, set the upstream to your own NextDNS profile that includes the OISD list, with Block Page enabled in the setting.
- Install .NET 6 SDK
- Clone this project, change the
proxydomain
inside Program.cs with your own Worker address - Run with
dotnet run
from the terminal
A normal run should only output All 400 succeeded
(you can change testcount
from 400 if you want, but a too large number might trigger Cloudflare/NextDNS DDoS protection), if you get a different result, open an issue.
