Yes but these show my router address each time. I'm not seeing the actual DNS server addres anytime I just keeo seeing I am not sure if the router is using the new nameservers OpenDNS I remember used to have this feature where they could tell if you opened a webpage – Somesh Mukherjee Aug 6 '13 at 4:05
If your computer is showing your router's address for the DNS, then that's exactly what you want. The router is using Google's DNS, and your PC is referring to the router for which servers to use. – Moses Aug 7 '13 at 3:34
i just need a way to be sure. I switched because DNS lookups on a lot of sites were failing. Some DNS lookups still fail, although the number has gone down. just need to be sure – Somesh Mukherjee Aug 7 '13 at 3:36
If you see your router address as the DNS for your computer, then you need to log into your router's control panel and look at what DNS entries it is using. – Darth Android Aug 7 '13 at 20:39
