CURLOPT_DNS_INTERFACE(3)				     curl_easy_setopt options					  CURLOPT_DNS_INTERFACE(3)

NAME

       CURLOPT_DNS_INTERFACE - set interface to speak DNS over

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_INTERFACE, char *ifname);

DESCRIPTION

       Pass a char * as parameter. Set the name of the network interface that the DNS resolver should bind to. This must be an interface name (not
       an address). Set this option to NULL to use the default setting (don't bind to a specific interface).

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

DEFAULT

       NULL

PROTOCOLS

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.33.0. This option also requires that libcurl was built with a resolver backend that supports this operation. The c-ares  backend
       is the only such one.

RETURN VALUE

       Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_NOT_BUILT_IN if support was disabled at compile-time.

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
