Best free and public DNS servers in 2021

DNS (Domain Name System) is a system which translates the domain names you enter in a browser to the IP addresses required to access those sites, and the best DNS servers provide you with the best service possible.

Your ISP will assign you DNS servers whenever you connect to the internet, but these may not always be the best DNS server choice around. Slow DNS servers can cause a lag before websites start to load, and if your server sometimes goes down, you may not be able to access any sites at all.
