How do I change the DNS on my PC?
Today, all the devices on your home network use fast and secure DNS, but you probably have devices that don't stay on the home network. When your laptop or smartphone connects to the free Wi-Fi of that dodgy internet cafe, you are also using the DNS server that the owner has chosen by default. Who needs cache poisoning when you have full control over DNS?
What are the steps to change the DNS on my laptop?
DNS servers translate friendly domain names into friendly IP addresses for machines. You may be using a DNS system offered by the ISP, the performance of which is uncertain. Switching to a third-party DNS service can both speed up your Internet activity and protect you from cunning DNS attacks. For more information, see: https://www.what-you-must-know.com/.
