You failed to close your code tags. This has caused some rather dramatic mangling. Please correct this, and wrap your input in code tags as well, since white space gets mangled in HTML. See How do I post a question effectively?.

Your MAC address code should read

/([\dA-Fa-f]{2}:[\dA-Fa-f]{2}:[\dA-Fa-f]{2}:[\dA-Fa-f]{2}:[\dA-Fa-f]{2 +}:[\dA-Fa-f]{2})/g);
or more concisely,
The code you posted (I think) was looking for literal '2's instead of a count ({2}). See Quantifiers in perlre.
