Sorry for my confusion - I have tried looking for tutorials explaining these concepts, but haven't found anything that made sense.
I am moving my hosting from mediatemple to ec2 and I understand the general idea of how DNS works, but I'm confused as to how the internals of nameservers / zone files work and what they do. How do I get my current domains registered with mediatemple to another registrar and how do I point them to my ec2 instance so I can start using it?
Any advice or links to more information are greatly appreciated. Thank you very much!
