A DNS, or Domain Name Server, is what helps translate human-friendly URLs into computer-friendly IP addresses. This is what enables your devices to connect to the internet and access the content you want to see.

When people change their DNS, it's usually to enhance either performance, security or both! And while there are many paid options, we're always fans of freebies. Below, we'll take a look at what to consider when switching your DNS and the 14 best free DNS servers to do it with.

What to consider when switching your DNS

A few things to note before we dive in:

Default DNS vs. third-party DNS – When you have internet service, your internet service provider (ISP) has a default DNS which your network uses to connect to the web. ISPs can collect data on customers and their internet activity. A third-party DNS can do the same, though it becomes more difficult to attribute the connection to specific individuals or households.
Free DNS vs. paid DNS – Beyond the obvious financial difference between a free and paid DNS, free options typically have fewer features. A paid DNS will have more advanced security and performance functionality, as well as better customer support and more customization options. Generally speaking, a free DNS will work for most purposes.
Public DNS vs. private DNS – A public DNS is available to the general population and it typically comes from your internet service provider or a dedicated DNS provider. A private DNS is typically used by companies to give employees easier access to internal-only websites/IP addresses. Typically, you're on a public DNS at home and either a private or public one at work.
