One way to think of the Domain Name System (or DNS) is as the phone book of the internet – DNS servers tell your machine what IP address domain names should point to.

For example, when you navigate to Google in your web browser (via, that domain is pointing you to You instead type this IP into your browser’s address bar, and you’ll see that it brings you to Google.

    As you can imagine, the database that tells our machines which domain points to which IP is constantly updating and changing. The DNS resolution process, handled by your DNS server, is one of the first choke points your browser hits when returning a web page.

    If you’ve never changed your DNS provider or you’re currently using one provided by your ISP, it could lead to slower speeds. Even worse, especially with small-market and local ISPs, your DNS server could actually be serving ads and other content that you otherwise shouldn’t be seeing.

    In this article, let’s talk about how you can manually change your DNS provider and some of the more trustworthy alternatives that you can switch to.

    Recommended DNS Servers To Use

    In 2015, Online Tech Tips published an article discussing the best free public DNS servers. While these options are still viable, a few new DNS providers have popped up since then.

    Let’s look into three of today’s best and most trusted options.

    Google Public DNS

    The benefits of using Google Public DNS include anycast routing, over-provisioning servers to protect against denial-of-service attacks, and load-balancing servers.

    Unlike many other DNS providers, Google Public DNS does not block or filter DNS requests unless the circumstance is considered to be extreme.

    Google Public DNS IPv6 addresses:

    • 2001:4860:4860::8888
    • 2001:4860:4860::8844

    OpenDNS is a public DNS provider that has been around since 2005. One of its main draws is protection against malicious websites that may be related to phishing or malware.

    OpenDNS provides other content filtering options, such as FamilyShield parental controls, which can be used to block sites that contain pornography.

    OpenDNS IPv6 addresses:

    • 2620:119:35::35

    Cloudflare DNS

    Cloudflare has been known for years due to its CDN and DDoS mitigation services. In April 2018, Cloudflare announced that it had acquired the prestigious address and would begin using it for its public DNS service.

    It’s advertised as the “fastest, privacy-first consumer DNS service,” claiming to process queries over twice as quickly as Google Public DNS.

    Cloudflare IPv4 addresses:


    Cloudflare IPv6 addresses:

    • 2606:4700:4700::1111
    • 2606:4700:4700::1001

    These are the three most trustworthy DNS provider options. While many may make claims regarding speed and performance, this will vary across locations. I’d highly recommend that you try each of them and see if you can notice any differences.

    If you’d like to look into an automated way of determining which DNS provider is fastest for your connection, Help Desk Geek previously published an article on utilities for changing your DNS servers.

    Set & Validate Your DNS Server

    Once you’ve decided on a DNS provider, input the preferred and alternate addresses in the window previously opened. Be sure to also tick the checkbox beside the Validate settings on exit option so that Windows runs a quick check to ensure that your DNS servers are working properly.

    When finished, I recommend checking out the What’s My DNS Server? website to do a second check.
