IP Validation

[Himanshu_Goyal]

Dear All Engineers,

You can validate user input IP address using the attached VI.

Can I`ve in LV11

Well,

in a limited way one can.

But your intention is ambiguous IMHO. It only accepts IP adresses in dot notation (1.2.3.4) on my system. If I provide a valid machine name ('pc1234') that can be resolved here, it returns 'Invalid'. Allthough the 'String to IP'-node returns a valid IP adress, but the 'IP to String'-node changes that to an IP in dot notation. And even if one changes that nodes control 'dot notation?' to false, it returns the complete machine name including the domain name (pc1234.mydomain.local) etc., which is not completely EQUAL to what was typed in. 

You should deside what you want to achieve, e.g. test for a well-defined adress or for an adress that could be resolved or whatever.

Just my € 0.02!

Hello Everyone, I used the proposed solution above but I faced an unexpected issue, if the input value is an invalid IP Address (e.g. "42" or "hello") the VI take at least 2000 ms to execute, therefore I have to do it manually for a faster validation, the attached image shows my solution.

It takes minimum execution time for almost any input value
