What is a public DNS server?

A public DNS server is a pair of IP addresses that belong to a free dns servers that can be accessed by everybody in the world. Unlike private DNS, public DNS are good for everyone who need a pair of domain name servers to replace their default dns server configuration.

Primary DNS Servers & Secondary DNS

This public dns list includes the primary DNS servers, which are often called "main DNS servers", and secondary DNS servers are also known as "alternative" dns servers. They are there to be used together, and never alone each one by their side, as it one fails, the other will take place to serve your existing dns queries.

DNS servers are known by many names, NS Servers, DNS Servers, dns ip addresses, private dns servers, etc, however, they are all the same, and they all will give you the same results.

Why should I change my current DNS Servers?

Your current DNS servers were probably assigned by your ISP, they all do it when you purchase your monthly internet connection service. This DNS servers are set in your local router or modem configuration. There a a few situations when you may need to change dns servers.

DNS Server not responding

This is the main reason on why you may think about switching dns servers on your local PC or network. Sometimes when you are facing negative caching issues, or not resolving websites and hosts as it should, a good idea is to change your DNS servers for one public free DNS server as the ones listed before.

But not only when you have problems you must change your local network DNS, it can also help you to improve website speed times. For example, most local DNS assigned by ISPs will never be as safe and fast as Google DNS servers, because of their anycast dns network.

Another reason to use other DNS servers from 3rd party companies and ISPs is to prevent your current ISP from taking full control of your web activity, as you will resolve using their DNS servers, and they can log any query you made.

On certain countries, using third party dns public servers is also useful to prevent website blocks as it happens in China, Siria, Iran, Venezuela and other countries were Internet goverment controls are very strict.

While the listed free dns servers are from different providers, you will have different levels of quality in their service.

We try to order the list by the best, fast and secure DNS, but you can choose as you like from very high quality dns providres like Google, OpenDNS, ATT, DNS.Watch, OpenNIC, FreeDNS, Verizon, Hurricane Electric, Norton ConnectSafe, UncesoredDNS, GreenTeamDNS, among many others.
