I'm not particularly concerned about points, but I *did* provide an accurate and correct answer, and it seems to me that it would be best to leave it here for other people to see if they have the same problem.

I have an application that tests connectivity to web and oracle servers. Recently I replaced all of the IP addresses that I'd hardcoded in my java app with DNS names that I keep in a local host file. For testing purposes, I have two hosts files, one with valid IP addresses and one with names that resolve to IP addresses that aren't reachable from my network. HOWEVER, when the application has been running using the &quot;good&quot; hosts file, it continues to run fine once I copy in the &quot;bad&quot; hosts file, even when I run &quot;ipconfig /flushdns&quot; after loading the &quot;bad&quot; hosts file.<br />
<br />
Does java use a separate internal dns cache? Any ideas?<br />

java and local dns cache

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
