Since, in a zone file, any line that begins with white space (tab or space
character) will use the same left hand side name as the previous line. So,
using AWK, you could do something like:
awk 'BEGIN{LHS=""}/^[WS]/{print LHS,$0;next}{print $0;LHS=$1}'
(Guaranteed NOT to work without lots of tweeks and testing. Use at your
own risk!)
Now, as to checking that "the records point to active hosts", well, I
won't even try for that. What do you mean by "active"?
But, as someone else said, look at "named-checkzone".
