I need to create a filename from the users IP# (using $ipaddress = $ENV{REMOTE_ADDR};). I have managed to capture the IP# (i.e 127.0.0.1) and change it to a proper filename (i.e. 127001) using $ipaddress =~ s/\.//g;, but I want to make it an "absolute" IP# (127000000001). I know you have to search for the first ".", count the number of intergers, and add the proper number of 0's to make three, then repeat the process, but I can't come up with a way of doing that. Any quick ideas?
Just for a little background, I want to do this so that I can log the number of login attempts to a page. I want to limit the number of attempts to 3, so I will create the file with the number of attempts incrementing 1 each time a login fails. If the number of login attempts exceeds 3, I will block the person from trying again for a specific amount of time.
Thanks!

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).
