ALIAS / ANAMEs RRs are a pseudo-type that is resolved during runtime of the authoritative server by querying a defined (set of) resolver(s) and dynamically returning their A and AAAA responses.

This is non-standard behaviour and e.g. when pointing an apex at another domain allows to react to changes of roaming virtual IPs.

We have some support for ANAME already. The linked I-D mentions that ALIAS is a pseudo-record type only supported by PowerDNS.
