no. a CNAME
record must be by itself, no other records can be present. you need to remove it to add an A
record.
A
is an ipv4 address, AAAA
is an ipv6 address, but CNAME
is neither, it is just a reference to another domain name, it clones its records.
If it's better to go with one or the other just depends on how often the addresses will change and who updates the final A
and AAAA
records.
