You could consider using OpenDns on your home internet connection for one of the four following reasons, or all of them. To provide an Ad blocker, faster internet, malware protection or a Family Firewall clean feed.

But first you need to secure your modem/router.

It’s very quick and easy to do from any device connected to your network, via cable or Wifi. All the information you need to do this is usually printed on the label of the modem/router itself.

The below example is from a Netgear N600. Click the image to make it larger. Your modem/router should have a similar label.


Using a browser like Internet Explorer, Google Chrome, Safari or Firefox etc login to the modem/router and change the default admin password and store it somewhere safe.

Now when you make changes you know they can’t be altered without the admin password.

Telstra Bigpond: If your internet is provided by Telstra Bigpond and you have a Telstra provided modem, you may be able to stop here and use Telstra Broadband Protect. If you do click here. If not continue reading.

Optus Cable: If you have Optus Cable internet and the Optus provided Netgear modem you may be able to stop here and simply download and install the Netgear Genie on one of your mobile devices, MAC or PC.

If you don’t have an Optus provided Netgear modem/router like the one above, read on.

Before you can begin setting up OpenDns you first need to find out whether or not you can edit your DNS records. Typically the DNS on most routers will be set to Automatic by the ISP.

Scan for the letters DNS next to a field which allows two or three sets of numbers, each broken into four groups of one to three numbers. Here are some screen shots of a few typical modem/routers and their DNS settings.

If you cannot find the option to change your DNS settings or they are greyed out, then your ISP may not allow you make these changes. You could ask a friend who knows more about computers and modem/routers to help you out or Contact Us. But if that’s the case then you won’t be able to use OpenDns. If you still wanted to go ahead the quickest and easiest option is to simply replace your current moden/router with a Netgear one because it has OpenDns actually built into it.

If you CAN change the DNS settings on your modem/router that’s good news because you can now continue to STEP 2


    1. It looks like a few people are having this issue

      I suggest you try downloading the Netgear Genie on a Windows PC and run it from there.

      Remember the idea of using the Netgear Genie when you have a Netgear router is that the settings applied with the Genie configure your router NOT the computer it is installed on. The idea of The Family Firewall initially is to set up a clean feed on your modem/router so all connected devices are protected.
      Don’t make the mistake of installing K9 or similar filters on your PC or MAC as this does not control your modem/router and will only protect the device it is installed on.


  1. The MAC install issue is to do with the version, you need to have 10.12.6 for it to install. As a workaround you could install the Genie on a smart phone or tablet.


  2. I tried to install Netgear with a MAC Capitan OS version, but it didn’t work. I then upgraded my MAC sftware tot he latest version macOS High Sierra and it worked. So Netgear must only be configured for the latest two MAC versions; Sierra and High Sierra
