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!

You can find more here : http://www.geekzilla.co.uk/BrowseExpressionArchive.htm

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}$
