ereg("^{([[:digit:]]+).([[:digit:]]+).([[:digit:]]+).([[:digit:]]+)$",} $REMOTE_ADDR, $parts);

$parts[1] is 202, $parts[2] is 197,...

What you want here is $parts[1].".".$parts[2]

Slightly simpler:

$aArray = explode('.', $REMOTE_ADDR);
echo $aArray[0].'.'.$aArray[1];

One could never guess I just love regular expressions. :-)

Thanks for bringing me back to Earth, vincent.
