Where to find domain name to existing EC2 instance

Question

I'm new AWS and I have to continue maintaining previous developer service that is hosted on AWS. The ec2 instance that is hosted has map to domain name of https://****c.k**g.g***an.org.au, however I couldn't find this domain name anywhere. I tried looking at route53, but there's no such domain name registered.

Please help, how do I find the domain name that is mapped to the EC2 instance? Where can I get that information. The reason because I want to deploy a new instance but with the same domain name.

Answer 1

Edit: Masking DNS for privacy reasons.

Are you sure your DNS is hosted by Route53? Running dig against k***.g****.org.au has the SOA held by ns1.mooball.net.

The whois for mooball.net returns register.com as the owner, so I would consider reaching out to your internal teams to see who holds that account, then check your DNS delegation settings by logging in to register.com.

Often times the client will control their own DNS, so it would also be worth confirming with your client where their root DNS (garvan.org.au) is hosted - you can then trace the subdomain delegation to see where it is ultimately hosted.

Answer 2

check route53 service in AWS , since the domain is served by https..it could be the domain mapped to a load balancer and the load balancer has the instance...anyway you can know from the route53 there you find all the records
