What is the DNS setting on a Router

Use a VPN

Have you considered using a VPN when you connect to the internet? A VPN is a great way to increase your security and anonymity while surfing.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes securely sharing your home network super simple. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

NordVPN birthday deal!

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

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:
