I have a domain registered with namecheap and its DNS records are managed by AWS Route 53. Currently, the domain points to a regular instance of EC2. I would like to configure a subdomain pointing to a separate instance of EC2 (in particular, an instance of Elastic Beanstalk). I have a Beanstalk instance installed (so if I am on an elastic IP for this instance, everything works fine).
The problem is that all the documents that I saw when adding the subdomain to Route 53 imply that the DNS records of the parent domain are still managed by the registrar. I don’t know where I need to add new NS records for the subdomain so that it points to the right thing.
