Using a custom DNS server is a simple way to increase your online privacy and security. Changing the DNS server on your Android smartphone is similar to changing the DNS server on other platforms. We’ll demonstrate how it works.
DNS is an abbreviation for “Domain Name System,” and it connects web servers to their domain names. Although your internet service provider provides its own DNS server, you may choose which one your devices use. There are several benefits to utilizing a custom DNS server.
So there you have it. You may now browse the web with a bit more protection on your Android device, which is always a good thing. If you’re not sure which DNS to use, popular options include OpenDNS, Google DNS, and Cloudflare DNS.
