IP URL regex validation

[Amit Dey1]

Hi , I have a requirement to validate IP URL and also anything after it , so I made this regex - ^(http[s]?:\/\/){0,1}(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])(.*)      , but this regex is not checking the last number part is 255+ or not I mean this regex is validating this IP URL also =  https://172.29.219.330 , here see the last part is 330 still it is validating , please help me in this matter

It is because of (.*) at the end. Remove that and try. It should look like below.

^(http[s]?:\/\/){0,1}(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])$

hi @Muhammad Khan but then I have to add anything after that part also like this https://172.29.219.33/(string)

so I mean after IP part user can add anything , but then it was not  checking  last part is 255+ or not

If user can add anything, then use below regex.

^(http[s]?:\/\/){0,1}(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|[01]?[0-9]?[0-9])(\/.*)?$
