BIND9 wildcard and unqualified name

Question

When an unqualified name (a name without a terminating dot) is encountered in a zone file, BIND9 appends the origin value ($ORIGIN directive) to it.

Example:

ns.domain.tld.    IN    A    SERVER_IP

The above line is equivalent to:

$ORIGIN    domain.tld.
ns                IN    A    SERVER_IP

I was wondering if it works for wildwards as well. For example, is this:

*.domain.tld.    IN    A    SERVER_IP

equivalent to

$ORIGIN    domain.tld.
*                IN    A    SERVER_IP

?

Answer 1

Yes, it doesn't make any difference in this respect that the owner name is a wildcard.

*.example.com.    IN    A    192.0.2.7

and

$ORIGIN    example.com.
*                IN     A    192.0.2.7

are equivalent.
