If all you need are external DNS addresses, etc. then you just use your
ISP's DNS. What we are talking about is if you are already running your
own DNS for internal nodes and for external name resolution as well.
When you do that you don't need to forward your requests to your ISP as
there is no benefit to doing so as you are already running a DNS which
can do that for you.
