Greetings, BlueLines.
Great little ditty -- especially in light of the fact it still works, nearly 12yrs. later!
One little nit;
Line 146 (my copy) reads:
return($x==4);
Which issues:
Use of uninitialized value $x in numeric eq (==) at ./scandns.pl line
+146.
Use of uninitialized value $x in numeric eq (==) at ./scandns.pl line
+146.
Changing the offending line to:
return($x);
Seems to squelch the complaint(s), and seemingly without ill.
Just thought I'd mention it, for you, or anyone else pondering it's use. :)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
