NAME

       CURLOPT_DNS_SERVERS - set preferred DNS servers

SYNOPSIS

       #include <curl/curl.h>

       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.
