       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_SERVERS, char *servers);

DESCRIPTION

       Pass  a  char  * that is the list of DNS servers to be used instead of the system default.
       The format of the dns servers option is:

       host[:port][,host[:port]]...

       For example:

       192.168.1.100,192.168.1.101,3.4.5.6

DEFAULT

       NULL - use system default

PROTOCOLS

       All

EXAMPLE

       TODO

AVAILABILITY

       This option requires that libcurl was built with a resolver  backend  that  supports  this
       operation. The c-ares backend is the only such one.

       Added in 7.24.0

RETURN VALUE

       Returns   CURLE_OK   if   the   option   is   supported,   CURLE_UNKNOWN_OPTION   if  not,
       CURLE_NOT_BUILT_IN if support was disabled  at  compile-time,  CURLE_BAD_FUNCTION_ARGUMENT
       when  given  an invalid server list, or CURLE_OUT_OF_MEMORY if there was insufficient heap
       space.
