IP regex

[tablex]

Hi,

I'm writing a regex, somehow the regex never matched.
after some analyzing it seemed to be the ip-part:

<?php
$sIP = "192.168.2.1";
if(!ereg('^{([01]?[0-9]{1,2}|2[0-4][0-9]|25[0-5].){3}([01]?[0-9]{1,2}|2[0-4][0-9]|25[0-5]){1}$',$sIP))}
{
echo"wrong";
}
else
{
echo"yay...";
}
?>

What am I doing wrong?

Thnx in advance!

You're only allowing a period in the first section if it follows 25x.
