can I set up DNS to route requests to an alternate subdomain with EC2?

Hi there!

Thank for posting your question here.

You can use Route 53 to create an A record that will point to that specific instance IP and You are correct, the ELB service is not a DNS service. Route 53 is the only DNS service available in AWS and Route 53 does support the creation of ALIAS records pointing to your load balancers.

I believe this answers you questions and concerns, and if not, then you are more than welcome for further engagement.

Thanks very much, I'll look into Route 53. Much appreciated! c
