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

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.
