Faster browsing experience as the company has servers across the world. This helps create less latency. The Company has more in-cache and this makes it faster to answer
Can be slow though you may not notice the difference as it is in milliseconds
Data tracking
Less cases of data tracking
Possibility of data tracking as the IP logs still remain with the ISP
Ease of use
DNS is easier to remember
You may need to write down the numbers as they are not easy to remember
One of the key reasons for having a private DNS is so that no one has access to your logging activity. This helps circumvent the blocking of certain sites. Google DNS deletes your IP queries after every 24-48 hours and this eliminates cases of data theft
The ISP still has access to your logs which may not be suitable for people who want to hide their web activity. ISP keep IP logs for a long time and this can expose you to data theft

Google DNS Overview

The Google DNS is a public domain name that is given by the company to users across the world. The DNS was started on 3rd December 2009 and functions as a recursive name server. As of 2018 the DNS had grown to become the biggest public DNS worldwide serving billions of queries. The Google DNS operates four IP addresses that are mapped out at the nearest operational server via anycast routing:

DNS blocking
DoH addresses
DoT address
IPv4 addresses

IPv6 addresses


Google DNS does not use conventional name servers like other DNS but instead has a custom designed implementation. This custom design conforms to the standards that are set forth by IEFT. The DNS has supported DNSSEC since 19th March 2013.

Google DNS does a good job of offering its clients the right privacy by ensuring that all IP address are deleted after 24-48 hours. These contrasts sharply with ISP that tend to store the data permanently in their data servers. On the downside there are some countries that have banned the use of the DNS as they see it as a means of circumventing access to certain sites. This had being the case with Turkey when they had an issue with Google DNS over Twitter. The DNS helped circumvent the blocking of Twitter which had been banned in the country. However, the company continues to make inroads across the world.
