Google Public DNS Servers

When you use Google Public DNS, you are changing your DNS "switchboard" operator from your ISP to Google Public DNS.

In most cases, the IP addresses used by your ISP's domain name servers are automatically set by your ISP via the Dynamic Host Configuration Protocol (DHCP). To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according to operating system and version (Windows, Mac or Linux) or the device (computer, phone, or router). We give general procedures here that might not apply for your OS or device; please consult your vendor documentation for authoritative information.

OpenNIC Public DNS Servers

OpenNIC is a non profit organisation and does not charge money for access to it’s DNS services including the proposal/request of new TLDs. It’s free to use and the servers are run by volunteers, so there’s no financial pressure to corrupt the OpenNIC system. You too could be one of the volunteers!

Have you ever typed a wrong URL into your browser and been redirected to a search page owned by your ISP? The domain you were typing in, the ads you click, and the search you input can all be collected by your ISP. This also is just annoying.

With OpenNIC when you reach a URL that is invalid, it lets your browser (which you are in control of) use its default response to the error, instead of trying to decide what’s best for you.
