some devices do not insert a 0x infront of hex ip
The result is that the ip could not be translated.
Maybe this could solve the problem?!

my($ip , $result , $crap);

#=========================================================
+==================
# Manche Geräte schicken die hexadezimale IP-Adresse
# ohne führendes "0X" welches eine Hexadezimale Zahl
# kennzeichnet
# Für den Fall das keine "0x" mitgeschickt wird unter
# Umständen die $hex_ip als ASCII Zeichen intepretiert.
# Diese Schleife wandelt das ASCII Zeichen in eine
# Hexadezimale Zahl um
# und setzt ein "0x" vor den String. Die so neu generierte
# Hexadezimale Zahl
# kann dann wiederum weiterverarbeitet werden

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>

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).
