Another common format for MAC address display is nnnn:nnnn:nnnn (common amongst Cisco gear, anyway).   In either case, it's the same 12 hex digits, only the delimiter and break-points change.

Is simple code that handles both formats possible?

    You could probably do something like:
    if $str =~ m!\.! {$str =~ s/(\.?[0-9a-eA-E]*)/(substr("0$1", -2))/ge;} else {$str =~ s/(:?[0-9a-eA-E]*)/(substr("0$1", -4))/ge;}
