Actually, I tested it further, and found that a regex of:
[0-9a-f.]
Works like:
[0-9a-f.]+

Following is a short script that I was writing for a friend. However, what I found in testing it,
was that the following interval {4} was acting like {4,}
Note specifically the test on $macadd4.
Enjoy....:)
Thanks,
Mike
