How to clear your DNS cache
You are likely aware that you need to clear your browser cache occasionally to keep everything running smoothly, but you are probably not aware of the DNS cache.
There are a few reasons why you should do this and if you've had any experience with websites and domain names, or even email, you will know what DNS is. Either way it's worth doing and takes just a few minutes.
Clearing your DNS cache can increase your connection speeds and foil potential attacks, but it's also general good housekeeping practice. We clear ours every few months.
