Can I create multiple hosted zones for the same domain name?
Q. Can I create multiple hosted zones for the same domain name? Yes. Creating multiple hosted zones allows you to verify your DNS setting in a “test” environment, and then replicate those settings on a “production” hosted zone.
Can I associate multiple VPCs with single hosted zone?
If you want to associate multiple VPCs that you created with one account with a hosted zone that you created with a different account, you must submit one authorization request for each VPC. When you authorize the association, you must specify the hosted zone ID, so the private hosted zone must already exist.
Where is the apex of a DNS zone?
The zone apex is where the SOA and NS (and often MX) records for a DNS zone are placed. They are DNS records whose name are the same as the zone itself. For example in in zone mydomainname.org you might have: mydomainname.org. 3600 IN SOA dns1.mydomainname.org. hostmaster.mydomainname.org.
Can a CNAME record be added at the apex of a zone?
Operationally a CNAME record effectively rewrites all other DNS records for that owner name (on the left-hand side) – for all record types – to the target name (the RDATA on the right-hand side). ISC BIND 9 will therefore not allow you to add a CNAME at the zone apex because this will create a broken zone and cause DNS resolution failures.
Can a subdomain be added to a parent domain?
Do not add a start of authority (SOA) record to the zone file for the parent domain. Because the subdomain will use Route 53, the DNS service for the parent domain is not the authority for the subdomain. If your DNS service automatically added an SOA record for the subdomain, delete the record for the subdomain.
What happens to the NS record set in azure DNS?
The NS record set at the zone apex (name ‘@’) gets created automatically with each DNS zone, and gets deleted automatically when the zone gets deleted. It can’t be deleted separately. This record set contains the names of the Azure DNS name servers assigned to the zone.
