Single elastic IP that can access multiple unique EC2 instances

Question

Is it possible to have a single elastic IP that can access multiple unique EC2 instances through some means (DNS/Route 53, a load balancer, etc)? 
For example, a single elastic IP would use DNS to access host01.ex.example.com, host02.ex.example.com, etc. Every instance is in the same region.

The [Elastic IP Address Limit Documentation](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html#using-instance-addressing-limit) points to AWS [DNS Documentation](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-dns.html#vpc-dns-hostnames) but I was wondering if this is something that can be handled automatically (maybe by the [Route 53 DNS Resolver](https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver.html))?

Answer

It's not clear what you're trying to do so that limits the scope of the answer I can give here. For example, what's the requirement for a single IP? What are you hosting? What protocol does it use?

In short, yes: You can use a load balancer which presents an elastic or public IP to the Internet and then distributes connections to instances "behind" that load balancer.
