 passing any IPV6 IP
But it is failed to validate ::ffff:12.12.12.12 format...
Please see my code...

bool IsValidIPv6String(wstring ipv6address)
{	
        wsmatch what;
        
        wregex
expression(L"^((([0-9A-Fa-f]{1,4}:){7}[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,
4}:){6}:[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){5}:([0-9A-Fa-f]{1,4}:)?[0
-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){4}:([0-9A-Fa-f]{1,4}:){0,2}[0-9A-Fa
-f]{1,4})|(([0-9A-Fa-f]{1,4}:){3}:([0-9A-Fa-f]{1,4}:){0,3}[0-9A-Fa-f]{1,
4})|(([0-9A-Fa-f]{1,4}:){2}:([0-9A-Fa-f]{1,4}:){0,4}[0-9A-Fa-f]{1,4})|((
[0-9A-Fa-f]{1,4}:){6}((\b((25[0-5])|(1\\d{2})|(2[0-4]\\d)|(\\d{1,2}))\b)
\\.){3}(\b((25[0-5])|(1\\d{2})|(2[0-4]\\d)|(\\d{1,2}))\b))|(([0-9A-Fa-f]
{1,4}:){0,5}:((\b((25[0-5])|(1\\d{2})|(2[0-4]\\d)|(\\d{1,2}))\b)\\.){3}(
\b((25[0-5])|(1\\d{2})|(2[0-4]\\d)|(\\d{1,2}))\b))|(::([0-9A-Fa-f]{1,4}:
){0,5}((\b((25[0-5])|(1\\d{2})|(2[0-4]\\d)|(\\d{1,2}))\b)\\.){3}(\b((25[
0-5])|(1\\d{2})|(2[0-4]\\d)|(\\d{1,2}))\b))|([0-9A-Fa-f]{1,4}::([0-9A-Fa
-f]{1,4}:){0,5}[0-9A-Fa-f]{1,4})|(::([0-9A-Fa-f]{1,4}:){0,6}[0-9A-Fa-f]{
1,4})|(([0-9A-Fa-f]{1,4}:){1,7}:))$");
        
        if(regex_match(ipv6address, what, expression))
        {
      // what[0] contains the whole string
      // what[1] contains the response code
      // what[2] contains the separator character
      // what[3] contains the text message.
      //if(msg)
       //  msg->assign(what[3].first, what[3].second);
          
          return true;
      
        }
        

        return false;
}

You're going to have to provide much more information:

The exact regular expression used,
The string you're matching against,
and if possible the code you're using.

Thanks, John.
