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.

If you can figure out how to disable the “chrome is out of date” message I would love you long time! It steals focus and brings chrome to the top. This is SUPER annoying on multi monitor setups 🙁
