It is a good idea to use public DNS servers like OpenDNS or Google DNS instead of ones provided by ISP.

There is now one more to the list – CloudFlare DNS.   (Accessing https://1.1.1.1 lists all the details about this service but as of now, the connectivity to it is intermittent.)

As per DNSPerf, it has the fastest lookup response (28% faster) among other DNS services and also doesn’t log any lookups for better privacy.

Configuring it is simple in Windows, just change the existing DNS settings to 1.1.1.1 and 1.0.0.1. It can also be done using a tool like DNS Jumper.

For Windows 10, here is how :

Access Control Panel (Windows key + I) and choose Network & Internet.

Click on Change Adapter options.

Right click on the adapter where the changes are to be made and click Properties.

For IPv4, change the primary and secondary DNS servers to 1.1.1.1 and 1.0.0.1

For IPv6, change them to 2606:4700:4700::1111 and 2606:4700:4700::1001

To verify if it is now active, open command prompt and run nslookup. It should display the new DNS server IP address.

All done.
