Good afternoon
On the website there are an example of a function to capture the network card address.
From what I know, the generated value shows, for example, "02-00-54-B5-4E-01".
My doubts.
Are there always letters?
Are these all letters from our alphabet, including possible special characters?
Or just another letter, if so what would they be?
Will the answer always be 6 sets as per this example?
Thanks
