This page shows how to change the DNS settings on the NetComm NB604N 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.
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.
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:
To get started configuring the NetComm NB604N DNS page you need to login to your router. If you are already logged in you can skip this step.
To login to the NetComm NB604N, follow our NetComm NB604N Login Guide.
If you followed our login guide above then you should see this screen.
You begin on the Status page of the NetComm NB604N router. To change the DNS or Domain Name System settings, click the choice on the left side of the page labeled Advanced Setup. Under that a new menu appears, from this new list, pick DNS, then DNS Server.
You are then taken to a page named DNS Server Configuration.
Scroll down past the two large boxes and tick the radio dot labeled Use the following Static DNS IP address.
Then under that, in the box titled Primary DNS server, enter the address of the DNS server that you want to be the primary one. This one will always be checked first.
Under that in the next box labeled Secondary DNS server, enter the address you want to be the alternate address of the DNS Server. This address will only be used if the first is inaccessible.
That is all there is to it, don't change anything else. Simply click Apply/Save and you're done.
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.
