help.dnsp.co
Ask the server what it can do.
What it does
Every option this site documents is also listed by the server itself. Ask help.dnsp.co for its TXT record and you get the current list, one name per option, generated by the running server rather than written down here.
The list comes from the server, so it reflects what the server currently answers. If something in it is not documented here, that option still works.
The list is long and specific, so an answer that comes back short, empty or altered means something rewrote the response between us and you.
Reading the answer
You are talking to us directly and nothing re-originated the query.
A resolver or proxy is asking on your behalf, which is normal when you did not use @dnsp.co.
Something inside your network is terminating DNS and forwarding it itself.
You are behind a resolver fleet. Repeat a few times before concluding anything.
Notes
- The answer is a set of names rather than prose, so it is easy to script against.
- Asked over UDP the list may be truncated. Add +tcp to be sure you have all of it.
