    Hi guys I have a general question for you all. Now I’m not sure the terminology that is used to describe this (maybe dns forwarding?) but I have heard its maybe bad for security and/or performance. Its where you enter your dns server addresses into the router and then each machine on your network each gets the address of your router for the DNS server which your router forwards. Is there any truth to the security and/or performance problem? I have tried to search on google without any luck. Of course doing this is a lot easier than entering dns addresses into each device you have on your network but is there any truth to the “rumors†of security / performance issues?

    your internal PC's should be looking to your router for DNS lookups. Not to the outside directly. This just saves bandwidth on multiple identical DNS lookups. I am not aware of any security concerns with that, though there are many things that sound alike in the DNS world.
