Thanks... It works... :)

Thanks for the Regex ..

Could you also include regular expression strings for other validations too,generally not found over net.

Thanks in advance!

It appears that the regex does not consider Ipv6

I've found another one at http://www.regular-expressions.info/examples.html:

\b(?:(?:25[0-5]|2[0-4][0-9]|01?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|01?[0-9][0-9]?)\b

thank you! works great

Thanks. You saved me a lot of time and trouble!

try this:

^([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){3}$

Wouldn't your expression allow for:

000.000.000.000 ?

I do this to check if I am on my home-server (PHP):

preg_match('/^127(?:\\.(?:25[0-5]|2[0-4][0-9]|1[0-9]{1,2}|[0-9]?)){2}\\.[1-9][0-9]{0,2}$/' , $SERVER['SERVERADDR'])

Regexes are good stuff.

Thanks Great working...

HI , I want regular expre.. for ip address with wild card support .

Can any body help me on this .

Hi i won't to fix the "zero" and "255" ending ip address allowing

Bellow the rgex that don't allow addresses like "x.x.x.255" or "x.x.x.0" it is good for IP address as is.

^([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){2}(\.([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-4]))$

And this regex (was sended by steve(thanx you very useful)) good for check network address or multicast addressing like x.x.x.255" or "x.x.x.0.

^([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){3}$
