What is the DNS setting on a Router

When you connect a router to the Internet it gets a few settings from your ISP automatically. One of the settings that the ISP sets in your router is the DNS setting. DNS stands for Domain Name System and it is used to convert Internet names into actual IP addresses. For instance, when you go to "google.com", your are really connecting to an IP address that is mapped through DNS to a number such as:

  • 173.194.33.73

This mapping happens automatically every time you visit any page on the Internet.

Why Change Your Router's DNS Setting

Some ISPs choose to abuse the DNS system and map unknown names to servers that they control. This can be done in a way that you don't know it is happening since your router is getting its DNS settings from your ISP. For instance, if you have one of these ISPs who is hijacking your DNS, and you try to surf the web to "some-random-site.com" and "some-random-site.com" does not exist, you might get a page back from your ISP with local advertisements on it.

By changing your DNS setting in your router you will effectively change the DNS setting for every computer on your network. This is because when a device is connected to your network your router automatically hands out its own DNS settings to that device. This way you can protect your entire network from ISP hijacking with just one setting.

What Should I Change My DNS To

There are 2 really great DNS servers on the Internet that you can choose from right now: Google Public DNS and OpenDNS. If you are not sure which one to pick then just use Google Public DNS.

When you change the DNS settings in your router, you usually have to enter a Primary and a Secondary setting. The secondary is only used if the primary can not be located. Here are common settings:

If you want to use Google Public DNS, use the following settings:

  • Primary: 8.8.8.8
  • Secondary: 8.8.4.4

If you want to use OpenDNS, use the following settings:

  • 208.67.222.222
  • 208.67.220.220
