dnsResolveEx not returns IP address values

Question

I am trying to use dnsResolveEx function in a script .pac but it not returns IP address values, all it can return is the value "0" zero;

Follow is my script:

function FindProxyForURLEx(url, host)
{
	var hostIP;
	hostIP = dnsResolveEx(host);
	
	if (shExpMatch(hostIP, "*:*"))
		return "DIRECT";
	else
		if (shExpMatch(hostIP, "*127.*") || 
		shExpMatch(hostIP, "*10.*") || 
		shExpMatch(hostIP, "*172.16.*") || 
		shExpMatch(hostIP, "*192.168.*"))
		return "DIRECT"
		
		else
			return "PROXY proxy.com.br:8080";
}

Could you help to understand if a failed to write or there is a bug on those function?

Hello there,

DNS results can be cached by your operating system or local network devices. If you're expecting an immediate change in DNS records, you might need to wait for the cached results to expire before the new records take effect.

Library or Tool Issues: If the dnsResolveEx function is part of a library or tool, check the documentation, community forums, or support channels for any reported issues or limitations. There might be updates, workarounds, or known bugs that you should be aware of.

Microsoft has a nice set of docs for the IPv6 Aware APIs.

http://msdn.microsoft.com/en-us/library/windows/desktop/gg308477(v=vs.85).aspx

The IPv4 APIs mostly operate the same way other then they do not support IPv6 addresses.

Hope this resolves your Query !!
