Flushing your DNS cache can help to fix host connection problems you may experience when accessing some web pages. To get a better Internet access performance, Google built a caching system, not only for site content but DNS as well. So yes, Google Chrome does have a built-in internal DNS caching system – a hidden feature that allows users to manually clear out the Chrome DNS host cache from within the browser itself.
Flushing out the Chrome DNS cache can prove useful, especially when you have changed the DNS settings. If clearing out the DNS cache from the operating system level does not fix the host connection problems, clearing up Chrome’s own DNS cache should do the trick.
This article will show you step by step how to clear the Chrome DNS cache.

When you want to send an instant message to someone else that’s on the same local network as you are, whether that be another family member or a co-worker in your office, why use an offsite chat server that leaves your messages open to interception by the company running the chat server or some other third party? This software will allow you to keep your local IM’s in your local network, and for added safety it also encrypts them! Plus, it supports multiple operating systems, unlike the proprietary chat client that might have come with your computer. It’s NOT for chatting with people elsewhere on the internet; if you need to set up secure connections with offsite chat clients then you may need to set up a private Prosody IM server. But for secure IM chats with people on your local network, this looks like just the thing!
