The ALIAS record provides a way to have CNAME-like behaviour on the zone apex.
In order to correctly serve ALIAS records in PowerDNS Authoritative Server 4.1.0 or higher with Artica 4.30 Service Pack instable 973 or Artica v4.40 ( Restart of DNS Service is required after upgrade)This record prevent the Attempting to add CNAME to xxx.xxx which already had existing records error
When the authoritative server receives a query for the A-record for example.net, it will resolve the A record for mywebapp.paas-provider.net and serve an answer for example.net with that A record.
When creating a new record, choose the type “'ALIAS”
- On the name set the host source ( if it is the domain itself, type the star “*” )
- Set the value you want to set as an alias.
- The alias is now added into your domain scope.
