Be sure to use the correct DNS record type for IP addresses in the service you're pointing to:

- AWS Elastic Beanstalk environment: A record (IPv4)
- Elastic Load Balancing (ELB) load balancer: A record (IPv4) or AAAA record (IPv6)
- Amazon Simple Storage Service (Amazon S3) bucket: A record (IPv4)
