By default, your computer is set to use the DNS configured in your router or modem which is Internet Providers DNS unless it has been changed. I always recommend using public dns servers, which you should see in this guide as they are most active and have a 99% uptime.

In this guide, we will be discussing on how to change the DNS from local or default (automatic) to Google’s DNS. Reason is, that Google DNS has a high uptime, almost 99.99% and more reliable then the ISP’s or Internet Provider’s DNS so switching it to public dns should resolve issues where the previous DNS is down, overloaded or slow to respond.

- Then, from the properties pane, click “Internet Protocol Version 4 (TCP/IPv4)” once so that it becomes highlighted in grey and select Properties again.
