pf » Reverse IP Address Lookup with ColdFusion + Java

I needed to do a reverse lookup on some IP addresses in a database today. I found that you can do this pretty easily with java, and just as easily with ColdFusion. Here it is:

<cfset inet_address = CreateObject("java", "java.net.InetAddress")>
<cfset host_name = inet_address.getByName("66.249.66.99").getHostName()>
<cfoutput>#host_name#</cfoutput>

In java this would simply be:

System.out.println( java.net.InetAddress.getByName("66.249.66.99").getHostName() );
