The parameter should be a char * to a zero terminated string which +must be URL-encoded in the following format: "https://host:port/path".

Even if you set a crazy value here, \fIcurl_easy_setopt(3)\fP will +still return \fICURLE_OK\fP. + +curl sends POST requests to the given DNS-over-HTTPS URL. + +To find the DOH server itself, which might be specified using a name, libcurl +will use the default name lookup function. You can bootstrap that by providing +the address for the DOH server with \fICURLOPT_RESOLVE(3)\fP. + +Disable DOH use again by setting this option to NULL. +.SH DEFAULT +NULL - there is no default DOH URL.
