Hi all,
Here is the regular expression for matching the valid ip
address.
^(25[0-5]|2[0-4]{0,1}[0-9]{0,1}|1[0-9]{1,2}|[0-9]{1,2})[.](25[0-5]|2[0-4]{0,1}[0-9]{0,1}|1[0-9]{1,2}|[0-9]{1,2})[.](25[0-5]|2[0-4]{0,1}[0-9]{0,1}|1[0-9]{1,2}|[0-9]{1,2})[.](25[0-5]|2[0-4]{0,1}[0-9]{0,1}|1[0-9]{1,2}|[0-9]{1,2})$

Let me know your comments.

Thanks,
