This will, of course, NOT WORK. The "blank" first field means to use
the same first field as the previous record. That is, both records
refer to www.WHATEVER.DOMAIN.

Then your "blank" record must have been closer after the SOA record.

This is a perfectly reasonable way to set the domain name to have a
specific IP address.
Note, of course, that the "@" value changes if you use a "$ORIGIN"
directive.
