DNS Server Settings to point to EC2 Instance for existing Domain

Question

These seems like such a simple question but I haven't found an answer other than "Transfer your domain name to Route 53"  
Here is what I have -  
I have an existing domain name registered with eNom. That registration's NDS server settings point to a shared hosting service that holds the existing website.  
I have an EC2 instance running IIS with a web site and service. This is associated with an Elastic IP address.  
  
My question is - what do I enter in the DNS server settings as a Name server to point to the site hosted by the EC2 instance?  
I can change the A record at the current host but that seems a little bit hacky.   
  
TIA,  
Chris

Accepted Answer

You can register your domain name where ever you like and you can have your domain  
DNS records where ever you like, they don't have to be the same place.  
  
You can keep your domain registered at eNom and use their name servers  
and set/point your domain to your EC2 ip  
  
or....   
  
keep your domain registered at eNom and set up your DNS records / zone  
at Route 53. While setting up your zone it will list what name servers to use.  
After setting up your records you can update your name servers at eNom to  
use the name servers listed in your Route 53 zone record  
  
or....  
  
set up your records at route 53 and then move your domain register to route 53 as well.  
  
all the above is perfectly acceptable. Just depends whos speed, pricing, service, interface you like best.

Thanks! - This is exactly the kind of answer I needed.  
I was thinking about the problem the wrong way so I couldn't recognize the answer when I read it. The text looks like it was copy and pasted right from the docs.  
  
So what I have is already correct. I reset the zone records to point to the EC2 ip.  
Now I can get back to work.
