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.
