I've a few questions in the mean time :) 1- What is exactly a supermaster (With examples if possible) for dummies? 2- Is it better to have the DB MySQL on the same server ns1, or on a separate one? 3- How to setup a 2nd Master ns2 dns server if possible? I mean, I want to have : two DNS masters two DNS slaves two separate DB MySQL (Synchronized with 3rd party (HowTos)
