CURLOPT_DNS_LOCAL_IP4(3)				     curl_easy_setopt options					  CURLOPT_DNS_LOCAL_IP4(3)

NAME

       CURLOPT_DNS_LOCAL_IP4 - IPv4 address to bind DNS resolves to

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_LOCAL_IP4, char *address);

DESCRIPTION

       Set  the  local	IPv4  address  that the resolver should bind to. The argument should be of type char * and contain a single numerical IPv4
       address as a string.  Set this option to NULL to use the default setting (don't bind to a specific IP address).

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL

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 7.33.0

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,	or
       CURLE_BAD_FUNCTION_ARGUMENT when given a bad address.

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

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL - use system default
