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:

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:

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

Change the DNS settings on a ZyXEL P-2812HNU-F1

If you followed our login guide above then you should see this screen.

This guide begins on the Device Information page of the ZyXEL P-2812HNU-F1 router. To setup the Domain Name System server, first click the link at the bottom of the page labeled Network Setting. Then, at the top of the page, choose LAN Setup.

Configure the DNS section of your ZyXEL P-2812HNU-F1

Scroll down this page until you see the heading of DNS Values. Notice how the DNS Server 1 has been filled in with the LAN IP Address. This is because the of DNS Proxy, it is checking with the router first to see if it needs a DNS server before continuing. As a result of this, we recommend setting both the WAN and the LAN side DNS servers, because it is not clear where the proxy is getting it's information from.

Use the drop down menu next to DNS Server 2 and pick the choice of User-Defined. Then, enter the primary address of the DNS server you want to use.

In the drop down menu of DNS Server 3, again choose User-Defined, and enter the secondary address of the DNS server in the space provided.

Click Apply when you are finished.

Remember that we also recommend setting the WAN side DNS server, unfortunately we do not have the screenshot for that page.

Possible Problems when Changing your DNS settings

Most devices on your network will not begin using the new DNS settings until they have been rebooted. After rebooting a device you can go to it's network settings and verify that it is using the DNS servers that you specified.
