Public DNS

A Public DNS (Domain Name System) is like a universal contact list for the internet. Just as your phone's contact list matches names to numbers, DNS servers match domain names (like 'www.example.com') to their corresponding IP addresses, which are necessary for devices to access websites. Public DNS servers are available for anyone to use. They are maintained by organizations offering an alternative to the default DNS servers provided by your internet service provider (ISP). These public servers can sometimes offer faster, more reliable, and more secure connections. However, they are called 'public' because they are accessible to any user on the internet.

The information provided by our "Public DNS" service is exceptionally current. We conduct hourly tests on a wide array of open-resolvers around the globe to ensure they are operational. Only those DNS servers that pass our rigorous testing are displayed on our service. This means that when you consult our list, you're seeing only the Public DNS servers that are confirmed to be working at the time of your query. This hourly update cycle ensures that you have access to the most reliable DNS servers at any given time, providing a dependable alternative for your internet queries.

You can use the Public DNS servers listed in our service by manually entering them into your device's network settings, such as 'resolv.conf' on Linux systems, or the DNS settings on other operating systems. Tools like 'host' and 'dig' can also be configured to query these servers directly. This can be beneficial if you're looking for faster DNS resolution or if you're trying to bypass local DNS filtering or censorship.

However, it's important to exercise caution. These servers are third-party open resolvers, and using them means that the operator of the DNS server could potentially log your DNS queries, which may include the websites you visit. This could lead to privacy concerns, as your browsing data might be exposed to someone other than your ISP. Therefore, it's crucial to use Public DNS servers from providers you trust and to be aware of their privacy policies. People who are knowledgeable about DNS and are aware of the implications of using third-party servers are best suited to make an informed decision about whether to use these services.
