Your logic is flawed. Instead of this: 
  if ($_ !~ /^zone \"$domain\" \{/ .. /\}\;/)

[download]
you should really have this: 
  unless (/^zone \"$domain\" \{/ .. /\}\;/)

[download]

Why? In your version you use the (/A/ .. /B/) syntax to extract a range of lines between /A/ being true and /B/ being true. When you test for ($_ !~ /A/ .. /B/) then you get everything between /A/ being false and /B/ being true. That's not what you want.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:

    < &lt;
    > &gt;
