How to Clean your DNS and Temp Files

Users have reported slow internet speeds in Windows 8. This is due to expired and invalid DNS records. Also known as “DNS Spoofing”. Other occurrences can be from web servers changing their IP address. To fix some of these issues you should flush your DNS and delete your temp files. Directions below.

What IS DNS?

DNS stands for “domain name system.” Domain names are the human-readable website addresses we use every day. For example, Google’s domain name is google.com. If you want to visit Google, you just need to enter google.com into your web browser’s address bar and your there!

However, your computer doesn’t understand where “google.com” is. Behind the scenes, the Internet and other networks use numerical IP addresses (“Internet protocol” addresses). Google.com is located at the IP address 173.194.39.78 on the Internet. If you typed this number into your web browser’s address bar, you’d also end up at Google’s website. Give it a try yourself!
