How to Configure DNS on Your Windows 7 PC

The Domain Name System (DNS) is provided by your ISP and could be slower than other alternatives. Here’s how to add an alternative DNS service to your Windows PC.

Note: This method applies to Windows 7 and the steps for Windows 10 will vary.

What is DNS?

DNS translates IP addresses to an easy to remember domain name. For example, if you type: into your browser address bar. It resolves to Think of DNS as the Internet’s phone book.

IP Address Bar

Remembering a name like is much easier than remembering the IP address.


Configure DNS on Your Windows PC

Google Public DNS provides a faster way to get to websites faster.

To add Google Public DNS to your Windows 7 or Vista computer, click Start and type: networks and sharing center into the search box and hit Enter.

Start Search

Next, click Change Adapter Settings.


In the Network Connections screen, right-click Local Area Connection then Properties.
Network Connections

Local Area Connection Properties comes up. Highlight Internet Protocol Version 4 (TCT/IPv4) then click Properties.


In the next screen, select Use the Following DNS Server Address.


Type: and in the Preferred and Alternate DNS Server fields. They can be in either order. Click OK.


Closeout of the other open Network Configuration windows. Then launch your web browser and test out various busy sites to see if they load faster.


That’s it. There are other alternate DNS services like OpenDNS and DynDNS you can try too. I’ll be covering those in future articles.

So far I’ve had great luck using Google Public DNS – especially while browsing in Chrome.

Other Alternative DNS Services

Here are the DNS settings for the three popular and free alternative DNS services out there:

    will this process work with windows xp? linux?

    • LL

      Yes, it will work with any device that connects to the network so long as you can change the DNS settings. Adding this to the XBOX now.

  2. Brian Burgess

    @azurehi: Yep. Works on any OS that allows you to change DNS settings. Including your router – which I will be covering in an article soon!

      I believe programming the router with OpenDNS is recommended, especially if you want to do blanket network filtering for your whole home or office. You can exempt specific computers by hard-coding other DNS servers on individual machines for non-filtered access. Helps prevent a lot of malware and viruses, I believe.

    I was able to use this trick one time when Comcast’s DNS servers were down for a few days.

  4. Curtis

    Or… use OpenDNS to get free content filtering for any network!

    Also pretty fast, and less evil than Google.

    • ejes

      I agree with Curtis.

      Do NOT use Google’s, use OpenDNS they even provide free malware filtering.


    i WAS going to ask if the google dns was faster than open dns..but i guess you haven’t gotten that far yet..BUT in case i’m wrong and you HAVE gotten that far….is it? lol

    • VOXPOP

      OOPS! i guess i shooda read the previous comments re google/open dns comparisons

      • Curtis Kline

        Sorry for the delay. No, personally I haven’t tried google’s DNS. I’ve just always been with OpenDNS. I hate slow loading pages, and I wouldn’t still use it, were it functionally slow. Any lag in DNS queries appears to be unnoticeable.

    I have changed DNS servers many times over the years, both Google and openDNS, and others. I have not found that any of them are faster than Comcasts defaults, which are assigned in your router dynamically. It’s a good learning experience, but don’t expect any changes in speed and security, IMHO.

      If anything it’s probably a bit more secure not using google for DNs. They already have your search data. Bit a bad idea not giving them your surfing data also. :)
