Whenever we enter google.com or yahoo.com, our computer contacts DNS servers and asks what IP Address is associated with both domain names. After getting the IP address, it connects to the visiting site’s web server.

Then, it loads and displays the web content. You can visit any site through its IP address, but we use the domain name because it’s easy to remember.

How Important is DNS?

Without DNS, the whole internet will not be accessible, and we will be rolled back to when the internet used to be a dream. We will be left with our computers, where we can only play offline games.

In the next part, we will discuss how different ISPs use different DNS servers. If you do not use a specific DNS server on your computer or router, you might use your ISP’s DNS servers.

Problems With DNS Servers

The DNS Servers assigned by ISPs are usually unstable and lead to problems connecting to different websites. You will get some unwanted browsing errors.

Some of the DNS errors include:

  • DNS Lookup Failed On Google Chrome
  • Err_Connection_Timed_Out Error
  • Err_Connection_Refused Error
  • Dns_Probe_Finished_Nxdomain Error
  • DNS Server Not Responding On Windows

The list doesn’t stop here; if you are getting any of these errors, you can blame your DNS. However, DNS-related issues can be resolved by switching to Public DNS servers.

Benefits of Using Public DNS Servers?

Google DNS

There are multiple reasons why tech guys still prefer Public DNS servers over ISPs. The most probable reason is to avoid unwanted errors. Another thing is that public DNS servers like Google DNS and OpenDNS can improve your internet browsing speed because they improve the resolution time.

ISPs block access to certain websites by resolving their names with the wrong IP addresses. By using a public DNS, you can easily avoid such blocking. Furthermore, some public DNS, like Google DNS, resolves hostnames faster than ISPs.

So, which is the best Public DNS Server? (Google DNS vs. OpenDNS)

I think Google Public DNS Server is the best and one of the fastest DNS servers that many users use. DNS Server Google ensures better security and a faster browsing experience.

The other best option is OpenDNS, a cloud-based DNS Server. With OpenDNS, you will get extended features like customizable filtering, theft and phishing protections, etc.
