Free Public DNS Server List

If you are having trouble with your internet connection speed, then use third-party DNS servers to improve your web browsing speed. It also can help you bypass the DNS servers of your local ISP (Internet Service Provider) and let your computer find the addresses of domain name that may be blocked by the ISP’s DNS servers.

What Does DNS Do?

DNS functionally acts similar to a phonebook but for IP (Internet Protocol) addresses. The system is used to translate a unique web address such as Rolo.org to the corresponding IP. Depending on the level of traffic experienced on a local network, there will be at least one, and normally two DNS servers configured to handle address look-up queries from client machines or devices. The primary DNS server is also referred to as the “Name Server” of the network and will store a list of all IP addresses on the local network. Depending on configuration, the server will also store a table of the addresses that have been recently accessed outside of the local network.

For any local network, a networked device will only need the address or location of one DNS server. If the networked device needs to conduct a DNS lookup, it will request it from the Name Server. If the address has been accessed recently, the server will do a quick look up in the cached addresses and send the response to the requesting computer. If there has not been a recent request for the address, then the local server will then request resolution from two or more other name servers. If there is no resolution found for the requested network address, an error will be returned to the end-user.

Here is a list of fast public DNS servers and free DNS server. They are all free, fast and is being a best alternative to your current DNS provider. For me Google Public DNS is the best and its working like a charm. Results of speed may differ for people living in different locations.

The listing of public DNS servers can change at any time depending on the funding and objectives of the provider offering the free service. Prior to changing the DNS configuration for your local computer or device, ensure you annotate the legacy server address in the event the public DNS server does not work. Consideration for the location of the public DNS server versus the device being used should also be taken into account as this can negatively impact performance if selecting a server located at distance from the end-user.
