Public DNS Servers

Sometimes you need a list of public DNS servers, there are some common ones and some not so common ones, here I present my go to list.  These are in no way endorsed, but I do use them all fairly regularly.  Where I say some services are Alternate Root these servers may give you different results than the rest.
