The Domain Name System (DNS) is an address book for the web, translating the web addresses that we use into the IP addresses used by computers to communicate. When you enter a URL like into your web browser, your browser queries the DNS server to get the IP address so it can access the web site.

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.

Switching to a free public DNS server can make a real difference, with more responsive browsing and lengthy 100% uptime records meaning there’s much less chance of technical problems.

If you’re already familiar with DNS servers, here’s the full list so you can get started immediately.

Warning! Many free DNS providers track, collect, and share your personal data — this is a serious risk to your privacy. To protect yourself, I recommend using a quality VPN at all times.

There’s custom firmware for some routers, DNS content-unblocking for a host of streaming media devices and smart TVs, and surprisingly capable VPN browser extensions for anything which can run them.

All that functionality could sound intimidating to VPN newbies, but ExpressVPN does more than most to help. An excellent support website is stuffed with detailed guides and tutorials to get you up and running. And if you do have any trouble, 24/7 live chat support is on hand to answer your questions.
