Ok, pingecho() is a deprecated back-compat wrapper for the ping method of Net::Ping. Running perldoc -m Net::Ping shows that ping returns an empty list if no $host is given. The default I mentioned was pure speculation. I don't see any way that an empty host string will return true, unless your inet_aton does so for empty argument.

Try distinguishing between undef and 0 as return values for pingecho. It is supposed to return undef for an unresolved host and 0 for an unreachable one. That will help you diagnose the problem.

How about just skipping the ping if the host string is not true?

if ($host) {
    if (pingecho($host,$timeout)) {
    #...
    }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
