In this article, we cover how to change the DNS servers on a router. The aim is to change the servers to use the OpenDNS IPv4 addresses 18.104.22.168 and 22.214.171.124.
While we have documentation for the most popular routers available here, we do not have the resources to list each single make and model of the router on the market. In general, the instructions below should suffice for most routers.
1. Open the preferences for your router.
Often, the preferences are set in your web browser, via a URL with numbers (example: http://192.168.0.1 or http://192.168.1.1). You may need a password.
If you're like us, and you set the router password long ago and cannot remember it now, you can often reset the password to the manufacturer default by pressing a button on the router itself.
Or preferences may be set via a specific application for your router, which you installed on your computer when you added the router.
2. Find the DNS server settings.
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. It might look like this:
3. Put in the OpenDNS server addresses as your DNS server settings and save/apply.
Please write down your current settings before entering the OpenDNS addresses, just in case.
4. Cache Flushing.
Once you have configured your DNS settings and saved them, we highly suggest that you flush your DNS resolver cache to ensure that your new DNS configuration settings take immediate effect.
5. Check your Settings.
Once you have configured your DNS, check the router has retained the settings.
