I think you should use DNAME, like CNAME but for domain.

Thanks Brian for your fast response,,,

you got exactly what I need (mirror entire domain to another), is there a way to do that?

I think you've misunderstood what ALIAS does.

ALIAS does not mirror an entire domain.  ALIAS is pseudo
resource-record, which expands to the dynamic lookup of another resource

It's typically used at the apex of a zone, where you might like to
insert a CNAME but you're not allowed to: CNAME cannot exist alongside
any other resource type, including NS and SOA.

; not allowed
@    NS    ns1.mydomain.com.
@    NS    ns2.mydomain.com.
@    CNAME    web1.cloudhost.com.

; solution
@    NS    ns1.mydomain.com.
@    NS    ns2.mydomain.com.
@    ALIAS    web1.cloudhost.com.

When someone looks up an A record for mydomain.com, they will get the A
record(s) for web1.cloudhost.com, which are dynamically looked up (via
the configured resolver) but returned as if they were stored in the
authoritative server.
