Configure OpenDNS at modem or router level?

Hi folks - 

This may be a dumb question. I have a DSL modem that has a Wi-fi router connected to it. The modem logs in to CenturyLink and uses their DNS currently dynamically. The wi-fi router also has DNS set to dynamic. Do I set OpenDNS settings at the modem or router level? Only the router is connected to the modem. All other connections go through the wifi router or ethernet ports. It seems like the logical place is first point of entry, which would be the modem, but I'm not sure.

 

Thanks,

--Dan

  It doesn't matter where you configure the OpenDNS resolver addresses as long as it works.  Simply try it out.

  I have an similar setup with Arris modem (where dns cannot be configured) and Asus router (where dns can be configured).  I followed directions and get the Oops message.  I've checked everything numerous time but still doesn't work. Any ideas?

  Post the complete plain text output of the following diagnostic command:

     nslookup -type=txt debug.opendns.com.

  Wow, that's for responding.  Here is the output:

  You're using the Dallas OpenDNS data center, and your IP address 73.20.57.195 is registered with dashboard network ID 26646229 which is hopefully yours.  You have configured the OpenDNS resolver addresses on the LAN/DHCP side of the router, so that they are propagated to all devices, or you have set your Windows computer manually to use OpenDNS.

  Therefore everything looks fine.  You shouldn't get the Oops message if you flushed your caches before.

  To follow up, are you getting an oops at http://welcome.opendns.com? There is another test at store.opendns.com which is currently experiencing some issues and incorrectly reporting not using OpenDNS. Based on the above result, it looks like you are using OpenDNS at the moment and that is your account information being returned.
