<pre><code>function ip2long(ip_address) {
  var parts = ip_address.match(/^(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})$/);
  return parts
    ? parts[1] * 16777216 + parts[2] * 65536 + parts[3] * 256 + parts[4] * 1
    : false;

@ Victor: That being said: I did take your idea for using fixed numbers, as I don't see any reason why not to, and it will greatly improve the speed of this function. Thx!

@ Victor: For minified versions we have php.min.js &amp;amp; in the near future our compiler will be able to compress a custom, smaller selection of functions for more speed &amp;amp; less size. For the original source however, we like to keep things as readable as possible.

Thanks a lot for contributing though!

A minimized version:

<pre><code>
function ip2long(a){if(a.match(/^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/)){var b=a.split('.');return(b[0]*16777216)+(b[1]*65536)+(b[2]*256)+(b[3]*1)}else{return&amp;quot;WTF? 0!&amp;quot;}}
</code></pre>
