OCI DNS 'A' record does not work

Oct 22, 2018 8:13PM

Summary

I have added an 'A' record in DNS. My understanding is, the A record will resolve to an IP address. After publish , it does not work

Here is what I did

1. create a private subnet, a public subnet

2. create 4 instances soa1 and soa2 in public subnet, soamt1 and soamt2 in private subnet.

3. created DNS, add 2 'A' records

soamt1.oci_lu.com 10.0.3.5

soamt2.oci_lu.com 10.0.3.6

4. publish the DNS

5. login to soa1 , try to ping soamt1.oci_lu.com,
ping: soamt1.oci_lu.com: Name or service not known

ping: soamt2.oci_lu.com: Name or service not known
