Or the more perlish (read : normal, not perverted brain have difficulties to understand it)
*grin*
while (@adrs=(gethostent())[4]) { map { $\="\n";print join '.',unpack'C4',$_} @adrs }
BTW I'm sure a Perl Guru, could tell me how to make this even smaller !
Please show me the light !

UPDATE
Ooops ! I suddenly realized that even if MY /etc/hosts contains only entries about my local machine, it might not always be the case (in fact it should often contains entries about other machines...).
So thousand apologizes, but all my posts in this thread do not resolve the problem...
But my code could be use to get the ip adresses of the machines in /etc/hosts...

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