Google Public DNS + ☀️ Benefits & How to Use

Written by Wilbur Woodham

Purpose of Google Public DNS.

As may you already be aware of, the DNS server has the purpose of matching Internet names and IP addresses. At times you indicate the website name, you are forwarded to the intended address. Each ISP has got its own designated name server. What are the privileges of Google’s DNS servers?

“Having outages in the Caledonia, Michigan area, the spectrum website keeps giving 500 and 404 errors when trying to login, and the spectrum DNS servers are down.”, — writes Twitter user @KarlBlessing.

What are the privileges?

1. Trust in the correct resolution of Internet names

When applying the Google DNS, you actually have a warranty that when you provide the website address you will encounter the original, instead of a substitute resource.

2. The rapidity of updating Google DNS databases

It sometimes occurs that the website amends IP. This may happen because of moving to another hosting resource or other technical details. On Google’s servers, such data is updated quickly, almost right away, whereas other servers, when asked for a hostname, can still provide an outdated IP address for a great duration of time (at least a couple of days).

3. Prevent blocking website provider

In case your Internet Service Provider blocks a certain resource via the DNS service by means of matching the domain name with another IP address (for instance,, with the help of registering Google DNS servers, you can eventually reach the blocked resource. In this manner, for instance, Turkey is blocking the Wikipedia site.

You have a range of options for applying Google’s public DNS:

  • on another device. In this instance, the privileges will be solely on this workstation.
  • on the router. Simultaneously, all appliances on the network will refer to the trouble-free DNS servers based on the default settings.
