CURLOPT_DNS_LOCAL_IP6(3) curl_easy_setopt options CURLOPT_DNS_LOCAL_IP6(3)NAME
CURLOPT_DNS_LOCAL_IP6 - IPv6 address to bind DNS resolves to
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_LOCAL_IP6, char *address);
DESCRIPTION
Set the local IPv6 address that the resolver should bind to. The argument should be of type char * and contain a single IPv6 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

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.

CURLOPT_FTP_SKIP_PASV_IP(3) curl_easy_setopt options CURLOPT_FTP_SKIP_PASV_IP(3)NAME
CURLOPT_FTP_SKIP_PASV_IP - ignore the IP address in the PASV response
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_SKIP_PASV_IP, long skip);
DESCRIPTION
Pass a long. If skip is set to 1, it instructs libcurl to not use the IP address the server suggests in its 227-response to libcurl's PASV
command when libcurl connects the data connection. Instead libcurl will re-use the same IP address it already uses for the control connec-
tion. But it will use the port number from the 227-response.
This option thus allows libcurl to work around broken server installations that due to NATs, firewalls or incompetence report the wrong IP
address back.
This option has no effect if PORT, EPRT or EPSV is used instead of PASV.

I have read many tutorials on bind and i understand the A,MX, CNAME records.
Internally, on a LAN we can install bind and create all these records and we can tell all PC and servers to use this bind as DNS server.that's fine.
On the Internet, when we have purchased a valid domain like... (5 Replies)
