How can I tell if the filtering is working?
OpenDNS has several test domains you can use to test the filtering settings on your computer.
My filters don’t work anymore. What’s wrong?
The most likely cause of filtering suddenly ceasing to apply is that your IP address has changed. Log into the Dashboard (http://dashboard.opendns.com) and compare what the IP address listed at the top of the screen is to your registered IP address. If the two don’t match, then your filters and logs will not function properly. You can update it from the Dashboard, or use our Dynamic IP Updater client to keep your IP address up to date.
If the IP address shown at the top of the Dashboard matches your registered IP address, then please ensure that you are using only OpenDNS server addresses on your network.
After you have verified those settings, you can visit http://www.opendns.com/welcome/ to test whether or not you are using OpenDNS.
How do I keep users on my network from circumventing my filtering policies?
Most operating systems do allow you to change the network settings on the local computer such that they bypass the DNS settings configured on the router. With that said, there are two ways in which you can prevent users on your network from bypassing OpenDNS:
1) Configure your users to use only Guest/Limited accounts on their computers. This way, they will not have administrative access to change the network settings on their machines.
2) You can obtain a router with the ability to force all DNS traffic over port 53 on the router, thus requiring everyone on the network to use the DNS settings defined on the router (in this case, OpenDNS). Unfortunately, this is not something we resources to assist with determining or configuring. You may want to check your router documentation or contact the manufacturer to see if this is possible with your device.
