AWS Route 53 A record shows up as CNAME in public DNS lookups

0

I have setup an AWS Route 53 A record (domain name to IP address) with simple routing. However when I use a some public DNS lookup tools this shows up as a CNAME record (domain name to domain name). What could be happening here?

  • Is Route 53 the SOA for the domain? You could be seeing one response when querying Route 53 directly versus another response from another public server if that service is not seeing Route 53 as the SOA / NS authority for the domain but another. This would be common when preparing a domain for migration to Route 53 but you have not yet pivoted the NS records to Route 53.

Hi,

I understand that when you do a DNS lookup a Route 53 CNAME record shows up when you had setup a Route 53 A record. I recommend you use the AWS provided tool see how Route 53 responds to your DNS. In addition, the documentation linked [1] provides further guidance on CNAME and A record nslookup query expectations.
