1- What is Norton DNS?

Norton DNS is a cloud-based Web filtering service that helps protect users from accessing malicious and phishing sites. Our new BETA service can also block access to sites with unwanted or offensive content.

2- How does it work?

The Domain Name System (DNS) is like a phone book. Each time your computer visits a web site, it needs to get the IP address of the site. Computers only connect to IP addresses, not human-friendly names. When Norton DNS is used, it delivers these IP addresses very fast, plus it does a quick check on each site to make sure that it isn’t bad. If it is, you are protected from the site but you will get detailed information on why we think that the site is bad. This information comes from our Safe Web database. You can search any site at http://safeweb.norton.com/. Norton Safe Web processes billions of requests each day to deliver ratings for users when they are searching on the Internet.

3- Where can I get Norton DNS?

Several options are available. To protect all Web-connected devices accessing the Internet via your home router, you can manually configure your home router to use Norton DNS (see router setup). To enable Norton DNS on your PC, if you are tech savvy, you can simply set your DNS server addresses to and (see PC setup). Otherwise you can download a small PC client that will automatically make the configuration changes for you.

4- How do I know if it is working?

After you manually change your DNS server addresses or you install the Norton DNS client, you can visit http://setup.nortondns.com/. This page will let you know if you are currently using Norton DNS.

5- Do I need software?

To get malware site blocking you can set your DNS servers manually on your PC, smart phone, or on your router. However, for laptop PCs we recommend that you install the PC client software to ensure that your DNS will always work, even when you are on a network that blocks alternative DNS servers. In addition, to use Norton DNS Web content filtering (BETA), you will need to install the Norton DNS PC client and sign in using your Norton Account username and password.

11- I want to use Norton DNS all the time on my smart phone, not just when I am connected to a WiFi hotspot. How do I make this work?

Currently Norton DNS protection is only available when connected to a WiFi network. Norton DNS protection is not available for Over The Air Web access from your carrier.

12- Does Norton DNS make my web browsing faster?

Everyone will have a different experience, but many users find that Norton DNS performs better and is more reliable than their default DNS provider. In fact, a number of serious DNS outages recently have proven how easy it is to switch to Norton DNS to ensure a reliable, fast Internet experience.

13- If I have Norton DNS do I need any other security solution?

Norton DNS only provides basic security — malware site blocking. It is not a substitute for a full, multi-layered, client-based security solution such as Norton Internet Security or Norton 360. On the other hand, lots of devices today (tablets, TVs, smart phones, etc.) are susceptible to some attacks and Norton DNS (BETA) can help keep you safe or protect your family from unwanted or offensive content.

14- How do I remove Norton DNS from my computer?

If you installed the Norton DNS client, simply uninstall it, and it will revert your DNS settings back to the previous settings.
