This complete list includes the best IPv4 and IPv6 public DNS servers in the world
The DNS (Domain Name System) is the system that translates the domain names user enter in the browser to the IP addresses required to access a website. Mostly, the user's computer is connected with the DNS servers assigned by an ISP. But those might not be the best DNS servers to consider.
Slow DNS servers may cause a lag before the website starts to load. And suppose if your DNS server goes down, you will not be able to access the required website. Switching to public DNS servers is the best choice and offers an alternative way to secure your connectivity. More reliability, durability, responsive time, and 100% uptime result in fewer technical issues.
The database contains all free and public DNS servers to choose to replace the original ones configured by your ISP.
This list includes the IPv4 and IPv6 public DNS servers in the world.
The public DNS server is the nameserver that networked computers may use to resolve the DNS query. That may be used in place of (or in addition to) the DNS servers assigned by your ISP. These are publicly available, and anyone can easily access them.
The public DNS server is also called a public recursive nameserver or public DNS resolver.
Even five years ago, ISP assigned DNS servers was sufficient to browse the internet. With time, the web pages get more complex.
Today, the DNS servers have to perform multiple lookups to display one website. That might increase the latency of the DNS server and hence slow down the browsing experience significantly.
According to YSlow, DNS lookups take 20 to 120 milliseconds to complete.
The main reasons to use the public DNS servers are

Like any other business, the DNS provider can also shut down. For example, Norton ConnectSafe was a well-recognized public DNS resolver, but it shut down its business in November 2018. So be aware of it and keep an eye on the service once you are settled with the one.
The internet speed also depends on how close a DNS resolver to your location. If your area is located near an OpenDNS PoP, then OpenDNS is the best option. If it's located almost 2,500 miles from the OpenDNS PoP, it's better to use a local DNS service.
Yes, you can mix the DNS servers. You can use the Google Public DNS as the primary DNS server and OpenDNS as your secondary DNS server; it will improve redundancy in case of failure of the Primary DNS server.
Changing your current DNS settings to a reliable public DNS server is safe. These changes are reversible and beneficial adjustments that will not harm your computer or network.
Usually, your ISP provides the DNS server that handles all the DNS queries from your computer.
In Windows 10, Open the cmd and run the "ipconfig /all" command. You will see that information in front of your DNS Servers heading.
