I have added public hosted zone
foo.mydomian.io in Route 53 and got my DNS provider to add name-servers for the sub-domain, however any records I create for mapping instances be it Type - A or CNAME don't work. If I run a
dig +trace ns I get a response which shows the AWS NS records for my subdomain, but I still reach instances using the names
I am not sure how to further troubleshoot this, or whom to seek support in this case, is it my DNS provider or Amazon?
What I also notice in the dig output is something like this in the answer section
foo.mydoamin.io. 3600 IN NS ns-1143.awsdns-14.org.mydomain.io. foo.mydoamin.io. 3600 IN NS ns-403.awsdns-50.com.mydomain.io. foo.mydoamin.io. 3600 IN NS ns-1764.awsdns-28.co.uk.mydomain.io. foo.mydoamin.io. 3600 IN NS ns-775.awsdns-32.net.mydomain.io.
I am wondering if the answer should atually be
foo.mydoamin.io. 3600 IN NS ns-1143.awsdns-14.org.
