Question

I am using ipconfig/all command and regular expression in java to find out the MAC address.

I am searching Physical Address in the output of ipconfig/all command.

But problem is I want regular expression to work on different locale i.e. it can find the Physical Address for any locale.

Thanks in advance.

Answer 1

Rather than searching for “Physical Address,” or any other localized version of that (which will require you to add a localized version each time you need to support a new language), you could write just one regex to find the MAC address itself.

Since we know that a typical MAC addresses is comprised of six groupings of two hex digits each, separated by colons, periods, or dashes, the following regex will do it:

([a-fA-F0-9]{2}[:\-\.]){5}[a-fA-F0-9]{2}

Explanation:
(two hex digits followed by a colon :, repeated 5 times) (the final two hex digits)
