doh - Man Page

doh sends DNS queries to a DNS-over-HTTPS (DoH) server. If no server URL is specified, it defaults to Cloudflare's public server.

Show the help output.

-k

Run in insecure mode. It completely switches off certificate checking of the DoH server!

-t

Test mode. Returns an exit code if there isn't a proper DoH response.

-v

Verbose mode. Shows lots of details from the underlying HTTPS connection and transfer.

-V

Show version number and exit.
