in reply to Re^3: How to increment a MAC Address?
in thread How to increment a MAC Address?

I did this:
# clear separators to obtain a hex string $mac =~ s/://g; # convert hex string into a dec number my $dec = hex($mac); # revert into a hex string $mac = sprintf("%012x", $dec+$add);

I don't see error here. I think it's used by context...

    My argument is with the word "dec" there. It's not decimal. It's just a number. In fact, it's more binary than it is decimal. {grin}

    The "hex" operator interprets a hex string or an octal string, converting them to a number. A number is an abstraction, without a numeric base, until it gets converted to a string again.

    Thus, you never really have a "decimal" number there. Just a number. Because you never printed it out.
