DNS query with ColdFusion

[thewolf]

Hi all,

I need to make a DNS query from within ColdFusion MX 6.1 to figure out the
Active Directories servers for a domain name (TXT records) .

I am looking for some example code to do that using the underlying Java
classes.

Any link?

Thanks a lot.

Attached is a function that works on all MX versions, i believe.

function GetHostName(address) {
// Variables
var iaclass="";
var addr="";

// Init class
iaclass=CreateObject("java", "java.net.InetAddress");

// Get address
addr=iaclass.getByName(address);

// Return the name
return addr.getHostName();
}
</cfscript>
