Route53 - Manual Update of IP address for A record of EBS Environment

Question

Hi,

I have a hosted zone testabc.com in Route53. Under this hosted zone, I have two records.
1. testabc.com    A      1.1.1.1
2. www.testabc.com   CNAME   testabc-env.elasticbeanstalk.com

For the above 2 records.

Record 1:
- 1.1.1.1 is just an example, we have to update this IP address very regularly, as we are using the IP address of the EBS environment

Record 2: 
- We link the EBS environment URL directly to it

My question is, because the IP address of the EBS environment changes regularly on AWS side, we have to manually update the the value for the A record shown above. Is there a recommended way to do that, so that we can access the website via both testabc.com and www.testabc.com ?

Just wondering, would it be possible for AWS to assign an elastic IP to the EBS environment, so that we don't need to update the IP value for the A record every now and then?

Thank you.

Answer

Hi,

I understand you want to access your website from both testabc.com and www.testabc.com. The issue you facing CX is due to CNAME limitation, where CNAME cannot co-exist with another record.
To solve this, when DNS is Hosted in R53, we normally advised CX to use A (alias) in root/parent domain. Below will be the necessary steps needed to take when creating an alias[1]:
- Sign in to the AWS Management Console and open the Route 53 console 
- In the navigation pane, choose Hosted zones
- Choose the name of the hosted zone that you want to use to route traffic to your Elastic Beanstalk environment
- Choose Create record
- Specify the following values
- Choose Create records
