I have been hosting with a few different dedicated server companies (server matrix, c i host, and a few others). I am now looking into moving everything into 1 central place and going to be using co-location with my own gear. How do I set up a server to be used JUST as a "name server?" Do most hosting companies have sepearate name servers or do the just use portions of their existing servers to run the name servers off of? Also I am thinking of setting up 2 seperate name server - servers. Any tutorials? Comments?
