title: Domain aliases using Amazon Route53
body: <p>I have just recently started using Route53 for managing the DNS records for my domain. I own two domain names, mydomain.com and mydomain.com.au.</p>
  
  <p>Is it possible to set up DNS records using Route53 such that mydomain.com.au is just simply an alias for mydomain.com. What I mean by this is that all DNS queries for xyz.mydomain.com.au will return the result of the same query for xyz.mydomain.com.</p>
