How to change DNS to see if Cloudflare really speeds up the network

Just a few days ago, Cloudflare launched its own DNS service 1.1.1.1 promises security and faster network connection speed instead of ISP's default DNS. Differences in speed may not be too big for you to change completely (in milliseconds only). But it does not take much time to check how DNS is, so if you are curious, you can try to find out.

Domain Name System (DNS) is a system to change domain names to IP addresses. The easiest way is to change the router settings, thereby automatically changing all devices joining the WiFi network to the new DNS.

The DNS is popular beside ISP's default DNS.

Google Public DNS

Main 8.8.8.8
Sub-section 8.8.4.4

OpenDNS

Main 208.67.222.222
Sub-208.67.220.220

Cloudflare

Main 1.1.1.1
Sub-1.0.0.1
